GeneratePBKDFKey

Parameter

Description

algorithm

The encryption algorithm for which to generate the key.

The supported algorithms are PBKDF2WithHmacSHA1, PBKDF2WithSHA1, PBKDF2WithSHA224, PBKDF2WithSHA256, PBKDF2WithSHA384, PBKDF2WithSHA512

string

The string to be used for conversion

salt

A random salt. The standard recommends a salt length of at least 64 bits (8 characters). The salt needs to be generated using a pseudo random number generator (e.g SHA1PRNG).

iterations

The number of PBKDEF iterations to perform. The recommended value for iterations is 1000 or more.

keysize

The key size in number of bits.
