cryptish v2.0.0

cryptish

A fast and furious set of crypto utilities.

(with fixedTimeComparison, randomBits, randomString from Cryptiles and copyright Eran Hammer)

Methods

randomString(<Number> size)

Returns a cryptographically strong pseudo-random data string. Takes a size argument for the length of the string and returns a safe string token (with / = + removed).

randomBits(<Number> size)

Returns a cryptographically buffer. Takes a size argument in bits.

generateSalt(<Number> size)

Returns a cryptographic salt value. Takes a size argument in bits, and returns a base64 encoded string.

hashPassword(<String> password, <String> salt)

Returns a pbkdf2 cryptographically hashed password. Takes password and salt as arguments.

verifyPassword(<String> password, <String> storedValue)

Returns true or false for a comparision of a pbkdf2 cryptographically hashed password.

fixedTimeComparison(<String> a, <String> b)

Compare two strings using fixed time algorithm (to prevent time-based analysis of MAC digest match). Returns true if the strings match, false if they differ.

binaryToBase64(<Buffer> buffer)

Convert a buffer to a base64 encoded string

base64ToBuffer(<String> string)

Convert a base64 encoded string to a binary buffer.

sha256(<String> string)

Perform sha256 hash on input returning hex digest.
