Random Key Generator Node Js

Posted : admin On 18.04.2020

(Node.js) Generate Encryption Key. Discusses symmetric encryption key generation techniques for block encryption algorithms such as AES, Blowfish, and Twofish, or for other algorithms such as ChaCha20. A Base32-Crockford encoded API Key generator, validator, and converter to turn UUIDs into human readable API Keys. Uuid; apikey. This generate random strings of 5 characters based on the current time. Example output is 4mtxj or 4mv90 or 4mwp1. The problem with this is that if you call it two times on the same second, it will generate the same string. The safer way is: (0 Math.random.9e6).toString(36) This will generate a random string of 4 or 5 characters, always diferent.

Installation

API

generate([len], [keys])

Generate cryptographically strong pseudo-random string, with given length.

  • len: the length of the generated string, default is 16
  • keys: optional keys, default is base62, including: 0-9, a-z, A-Z

generateDigits([len])

Generate random digits, with given length. optional keys: 0-9

  • len: the length of the generated string, default is 16

Random Key Generator Node Js Function

generateBase30([len])

Generate random string that is easy to read by human, with given length. Bitcoin private reddit.

optional keys: 1-9, A-Z exclude(E, G, I, J, O) for human read

  • len: the length of the generated string, default is 16

Usage for JS

LICENSE

The Crypto.getRandomValues() method lets you get cryptographically strong random values. The array given as the parameter is filled with random numbers (random in its cryptographic meaning).

To guarantee enough performance, implementations are not using a truly random number generator, but they are using a pseudo-random number generator seeded with a value with enough entropy. The PRNG used differs from one implementation to the other but is suitable for cryptographic usages. Implementations are also required to use a seed with enough entropy, like a system-level entropy source.

getRandomValues() is the only member of the Crypto interface which can be used from an insecure context.

Syntax

Key Generator

Parameters

typedArray
An integer-based TypedArray, that is an Int8Array, a Uint8Array, an Int16Array, a Uint16Array, an Int32Array, or a Uint32Array. All elements in the array are overwritten with random numbers.

Return value

The same array passed as typedArray but with its contents replaced with the newly generated random numbers. Note that typedArray is modified in-place, and no copy is made.

Exceptions

This method can throw an exception under error conditions.

QuotaExceededError
The requested length exceeds 65,536 bytes.

Usage notes

Don't use getRandomValues() to generate encryption keys. Instead, use the generateKey() method. There are a few reasons for this; for example, getRandomValues() is not guaranteed to be running in a secure context.

There is no minimum degree of entropy mandated by the Web Cryptography specification. User agents are instead urged to provide the best entropy they can when generating random numbers, using a well-defined, efficient pseudorandom number generator built into the user agent itself, but seeded with values taken from an external source of pseudorandom numbers, such as a platform-specific random number function, the Unix /dev/urandom device, or other source of random or pseudorandom data.
