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
|
Hashing algorithm used for generating key. At present only the PBKDF2WithHmacSHA1 is supported by Lucee.
|
|
|
passphrase
string,
required
|
Passphrase to be hashed.
|
|
|
salt
string,
required
|
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
|
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
|
The length in bytes of the key to generate.
|
128
|
Examples
dump(generatePBKDFKey("PBKDF2WithHmacSHA1", "secret", "salty", 5000, 128));// Y0MCpCe3zb0CNJvyXNUWEQ==
