- Nov 14, 2019 Generate a Random Password. For any of these random password commands, you can either modify them to output a different password length, or you can just use the first x characters of the generated password if you don’t want such a long password. Hopefully you’re using a password manager like LastPass anyway so you don’t need to memorize them.
- Mar 12, 2020 Run the madpwd3 utility to generate the encrypted password. The madpwd3 utility allows for the key and iv to be entered either from a file or directly on the command line. Use the -keyfile and -ivfile options to specify as a file or use the -key and -iv options to enter them at the command prompt.
Your Secret Key keeps your 1Password account safe by adding another level of security on top of your Master Password. Your Secret Key is 34 letters and numbers, separated by dashes. It’s stored on devices you’ve used to sign in to your account, and in.
-->Azure Key Vault is a cloud service that provides a secure store for secrets, such as keys, passwords, certificates, and other secrets. This quickstart focuses on the process of deploying a Resource Manager template to create a key vault and a secret.
Resource Manager template is a JavaScript Object Notation (JSON) file that defines the infrastructure and configuration for your project. The template uses declarative syntax, which lets you state what you intend to deploy without having to write the sequence of programming commands to create it. If you want to learn more about developing Resource Manager templates, see Resource Manager documentation and the template reference.
If you don't have an Azure subscription, create a free account before you begin.

Review the template
The template used in this quickstart is from Azure Quickstart templates.
Two Azure resources are defined in the template:
- Microsoft.KeyVault/vaults: create an Azure key vault.
- Microsoft.KeyVault/vaults/secrets: create an key vault secret.
More Azure Key Vault template samples can be found here.
Deploy the template
- Select the following image to sign in to Azure and open a template. The template creates a key vault and a secret.
- Select or enter the following values.Unless it is specified, use the default value to create the key vault and a secret.
- Subscription: select an Azure subscription.
- Resource group: select Create new, enter a unique name for the resource group, and then click OK.
- Location: select a location. For example, Central US.
- Key Vault Name: enter a name for the key vault, which must be globally unique within the .vault.azure.net namespace. You need the name in the next section when you validate the deployment.
- Tenant Id: the template function automatically retrieves your tenant ID. Don't change the default value.
- Ad User Id: enter your Azure AD user object ID that you retrieved from Prerequisites.
- Secret Name: enter a name for the secret that you store in the key vault. For example, adminpassword.
- Secret Value: enter the secret value. If you store a password, it is recommended to use the generated password you created in Prerequisites.

not simple. So here is some totally random raw material, generated just for YOU, to start with. Every time this page is displayed, our server generates a unique set of custom, high quality, cryptographic-strength password strings which are safe for you to use: |
64 random hexadecimal characters (0-9 and A-F):
|
63 random printable ASCII characters:
|
63 random alpha-numeric characters (a-z, A-Z, 0-9):
|
Click your web browser's 'refresh' button a few times and watch the password strings change each time. What makes these perfect and safe? Every one is completely random (maximum entropy) without any pattern, and the cryptographically-strong pseudo random number generator we use guarantees that no similar strings will ever be produced again. Also, because this page will only allow itself to be displayed over a snoop-proof and proxy-proof high-security SSL connection, and it is marked as having expired back in 1999, this page which was custom generated just now for you will not be cached or visible to anyone else. Therefore, these password strings are just for you. No one else can ever see them or get them. You may safely take these strings as they are, or use chunks from several to build your own if you prefer, or do whatever you want with them. Each set displayed are totally, uniquely yours — forever. The 'Application Notes' section below discusses various aspects of using these random passwords for locking down wireless WEP and WPA networks, for use as VPN shared secrets, as well as for other purposes. The 'Techie Details' section at the end describes exactly how these super-strong maximum-entropy passwords are generated (to satisfy the uber-geek inside you). |
Application Notes: A note about 'random' and 'pseudo-random' terminology: Throughout this page I use the shorthand term 'random' instead of the longer but more precise term 'pseudo-random'. I use the output of this page — myself — for any purpose, without hesitation, any time I need a chunk of randomness because there is no better place to find anything more trusted, random and safe. The 'pseudo-randomness' of these numbers does not make them any less good. There are ways to generate absolutely random numbers, but computer algorithms cannot be used for that, since, by definition, no deterministic mathematical algorithm can generate a random result. Electrical and mechanical noise found in chaotic physical systems can be tapped and used as a source of true randomness, but this is much more than is needed for our purposes here. High quality algorithms are sufficient. The deterministic binary noise generated by my server, which is then converted into various displayable formats, is derived from the highest quality mathematical pseudo-random algorithms known. In other words, these password strings are as random as anything non-random can be. This page's password 'raw material': The raw password material is provided in several formats to support its use in many different applications. Each of the password strings on the page is generated independently of every other, based upon its own unique pseudo-random binary data. So there is no underlying similarity in the data among the various format passwords. 64 hex characters = 256 binary bits: |
|
Each of the 64 hexadecimal characters encodes 4 bits of binary data, so the entire 64 characters is equivalent to 256 binary bits — which is the actual binary key length used by the WiFi WPA pre-shared key (PSK). Some WPA-PSK user interfaces (such as the one in Windows XP) allows the 256-bit WPA pre-shared key to be directly provided as 64 hexadecimal characters. This is a precise means for supplying the WPA keying material, but it is ONLY useful if ALL of the devices in a WPA-protected WiFi network allow the 256-bit keying material to be specified as raw hex. If any device did not support this mode of specification (and most do not) it would not be able to join the network. Using fewer hex characters for WEP encryption: If some of your WiFi network cannot support the newer and much stronger (effectively unbreakable when used with maximum-entropy keys like these) WPA encryption system, you'll be forced either to run two WiFi networks in parallel (which is totally feasible — one super-secure and one at lower security) or to downgrade your entire network to weaker WEP encryption. Still, ANY encryption is better than no encryption. WEP key strength (key length) is sometimes confusing because, although there are only two widely accepted standard lengths, 40-bit and 104-bit, those lengths are sometimes confused by adding the 24-bit IV (initialization vector) counter to the length, resulting in 64-bit and 128-bit total key lengths. However, the user only ever specifies a key of either 40 or 104 binary bits. Since WEP keys should always be specified in their hexadecimal form to guarantee device interaction, and since each hex digit represents 4 binary bits of the key, 40 and 104 bit keys are represented by 10 and 26 hex digits respectively. So you may simply snip off whatever length of random hex characters you require for your system's WEP key. Note that if all of your equipment supports the use of the new longer 256/232 bit WEP keys, you would use 232/4 or 58 hexadecimal characters for your pre-shared key. 63 printable ASCII characters hashed down to 256 binary bits: |
|
The more 'standard' means for specifying the 256-bits of WPA keying material is for the user to specify a string of up to 63 printable ASCII characters. This string is then 'hashed' along with the network's SSID designation to form a cryptographically strong 256-bit result which is then used by all devices within the WPA-secured WiFi network. (The ASCII character set was updated to remove SPACE characters since a number of WPA devices were not handling spaces as they should.) The 63 alphanumeric-only character subset: |
|
If some device was not following the WiFi Alliance WPA specification by not hashing the entire printable ASCII character set correctly, it would end up with a different 256-bit hash result than devices that correctly obeyed the specification. It would then be unable to connect to any network that uses the full range of printable ASCII characters. Since we have heard unconfirmed anecdotal reports of such non-compliant WPA devices (and since you might have one), this page also offers 'junior' WPA password strings using only the 'easy' ASCII characters which even any non-fully-specification-compliant device would have to be able to properly handle. If you find that using the full random ASCII character set within your WPA-PSK protected WiFi network causes one of your devices to be unable to connect to your WPA protected access point, you can downgrade your WPA network to 'easy ASCII' by using one of these easy keys. And don't worry for a moment about using an easy ASCII key. If you still use a full-length 63 character key, your entire network will still be EXTREMELY secure. And PLEASE drop us a line to let us know that you have such a device and what it is! Shorter pieces are random too: A beneficial property of these maximum entropy pseudo-random passwords is their lack of 'inter-symbol memory.' This means that in a string of symbols, any of the possible password symbols is equally likely to occur next. This is important if your application requires you to use shorter password strings. Any 'sub-string' of symbols will be just as random and high quality as any other. When does size matter? The use of these maximum-entropy passwords minimizes (essentially zeroes) the likelihood of successful 'dictionary attacks' since these passwords won't appear in any dictionary. So you should always try to use passwords like these. When these passwords are used to generate pre-shared keys for protecting WPA WiFi and VPN networks, the only known attack is the use of 'brute force' — trying every possible password combination. Brute force attackers hope that the network's designer (you) were lazy and used a shorter password for 'convenience'. So they start by trying all one-character passwords, then two-character, then three and so on, working their way up toward longer random passwords.
Note that while this 'the longer the better' rule of thumb is always true, long passwords won't protect legacy WEP-protected networks due to well known and readily exploited weaknesses in the WEP keying system and its misuse of WEP's RC4 encryption. With WEP protection, even a highly random maximum-entropy key can be cracked in a few hours. (Listen to Security Now! episode #11 for the full story on cracking WEP security.) The Techie Details: Since its introduction, this Perfect Passwords page has generated a great deal of interest. A number of people have wished to duplicate this page on their own sites, and others have wanted to know exactly how these super-strong and guaranteed-to-be-unique never repeating passwords are generated. The following diagram and discussion provides full disclosure of the pseudo-random number generating algorithm I employed to create the passwords on this page: |
While the diagram above might at first seem a bit confusing, it is a common and well understood configuration of standard cryptographic elements. A succinct written description of the algorithm would read: 'Rijndael (AES) block encryption of never-repeating counter values in CBC mode.' CBC stands for 'Cipher Block Chaining' and, as I describe in detail in the second half of Security Now! Episode #107, CBC provides necessary security in situations where some repetition or predictability of the 'plaintext' message is present. Since the 'plaintext' in this instance is a large 128-bit steadily-increasing (monotonic) counter value (which gives us our guaranteed never-to-repeat property, but is also extremely predictable) we need to scramble it so that the value being encrypted cannot be predicted. This is what 'CBC' does: As the diagram above shows, the output from the previous encryption operation is 'fed back' and XOR-mixed with the incrementing counter value. This prevents the possibility of determining the secret key by analysing successive counter encryption results. One last detail: Since there is no 'output from the previous encryption' to be used during the encryption of the first block, the switch shown in the diagram above is used to supply a 128-bit 'Initialization Vector' (which is just 128-bits of secret random data) for the XOR-mixing of the first counter value. Thus, the first encryption is performed on a mixture of the 128-bit counter and the 'Initialization Vector' value, and subsequent encryptions are performed on the mixture of the incrementing counter and the previous encrypted result. The result of the combination of the 256-bit Rijndael/AES secret key, the unknowable (therefore secret) present value of the 128-bit monotonically incrementing counter, and the 128-bit secret Initialization Vector (IV) is 512-bits of secret data providing extremely high security for the generation of this page's 'perfect passwords'. No one is going to figure out what passwords you have just received. How much security do 512 binary bits provide? Well, 2^512 (2 raised to the power of 512) is the total number of possible combinations of those 512 binary bits — every single bit of which actively participates in determining this page's successive password sequence. 2^512 is approximately equal to: 1.34078079 x 10^154, which is this rather amazing number:
