Generate a cryptographically strong random string
Deno module based on crypto-random-string. Useful for creating an identifier, slug, salt, PIN code, fixture, etc.
import { cryptoRandomString } from "https://deno.land/x/[email protected]/mod.ts"
// or
import { cryptoRandomString } from "https://github.com/piyush-bhatt/crypto-random-string/raw/main/mod.ts"NOTE: Outputs shown below are merely examples. The function will generate random string each time.
cryptoRandomString({length: 10}); // '0696cb9e70'
cryptoRandomString({length: 10, type: 'base64'}); // 'dw3mgWC5uO'
cryptoRandomString({length: 10, type: 'url-safe'}); // '0pN1Y2Jz.X'
cryptoRandomString({length: 10, type: 'numeric'}); // '1639380067'
cryptoRandomString({length: 6, type: 'distinguishable'}); // 'H4HH5D'
cryptoRandomString({length: 10, type: 'ascii-printable'}); // '#I&J.GP./9'
cryptoRandomString({length: 10, type: 'alphanumeric'}); // 'ZtgC2J6aU5'
cryptoRandomString({length: 10, characters: 'abc'}); // 'abcabccbcc'Returns a randomized string. Hex by default.
Type: object
Required
Type: number
Length of the returned string.
Type: string
Default: 'hex'
Values: 'hex' | 'base64' | 'url-safe' | 'numeric' | 'distinguishable' | 'ascii-printable' | 'alphanumeric'
Use only characters from a predefined set of allowed characters.
Cannot be set at the same time as the characters option.
The distinguishable set contains only uppercase characters that are not easily confused: CDEHKMPRTUWXY012458. It can be useful if you need to print out a short string that you'd like users to read and type back in with minimal errors. For example, reading a code off of a screen that needs to be typed into a phone to connect two devices.
The ascii-printable set contains all printable ASCII characters: !"#$%&\'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~ Useful for generating passwords where all possible ASCII characters should be used.
The alphanumeric set contains uppercase letters, lowercase letters, and digits: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789. Useful for generating nonce values.
Type: string
Minimum length: 1
Maximum length: 65536
Use only characters from a custom set of allowed characters.
Cannot be set at the same time as the type option.
