GeneratePBKDFkey()

edit

Implementation of Password-Based Key-Derivation Function (PBKDF).

Introduced: 5.0.0.0

GeneratePBKDFkey( algorithm=string, passphrase=string, salt=string, iterations=numeric, keySize=numeric );

Returns: String

Argument Description Default
algorithm
string, required 		edit

Hashing algorithm used for generating key

Example Values:

  • PBKDF2WithHmacSHA1
  • PBKDF2WithHmacSHA384
  • PBKDF2WithHmacSHA512/256
  • PBKDF2WithHmacSHA256
  • PBKDF2WithHmacSHA512/224
  • PBKDF2WithHmacSHA224
  • PBKDF2WithHmacSHA512
passphrase
string, required 		edit

Passphrase to be hashed.
salt
string, required 		edit

A random salt. It is recommended that you used something like the GenerateSecretKey function to generate a random salt, for example GenerateSecretKey( 'AES' , '256' ).
iterations
numeric, optional 		edit

The number of PBKDF iterations to perform. A minimum recommended value is 1000, however a value between 50,000 and 100,000 is recommended. You can also make this a random value, using something like the randRange() function, for example randRange(50000, 100000, 'SHA1PRNG').

4096
keySize
numeric, optional 		edit

The length in bytes of the key to generate.

128

Examples

edit 
	dump(generatePBKDFKey("PBKDF2WithHmacSHA1", "secret", "salty", 5000, 128));// Y0MCpCe3zb0CNJvyXNUWEQ==
