crypt.generatebytes

Generates size random bytes, and returns them encoded in base64.

crypt.generatebytes(size: number): string

The returned string’s length is 4 * math.ceil(size / 3) - implying crypt.generatebytes(10) returns a 16-character string.

Most commonly used to generate IVs, salts, nonces, and request tokens.

Parameters

Parameter	Type	Description
size	number	Number of raw bytes to generate before base64-encoding.

Returns

string - sequence of random bytes, encoded in base64.

Example

Pull 16 random bytes for use as a session ID, request nonce, or salt.

Typically used to generate secure IVs or temporary nonces.
