PBKDF2

PBKDF2 applies a pseudorandom function, such as hash-based message authentication code (HMAC), to the input password or passphrase along with a salt value and repeats the process many times to produce a derived key, which can then be used as a cryptographic key in subsequent operations. The added computational work makes password cracking much more difficult, and is known as key stretching.

The PBKDF2 key derivation function has five input parameters:

DK = PBKDF2(PRF, Password, Salt, c, dkLen)

where:

• PRF is a pseudorandom function of two parameters with output length hLen (e.g. a keyed HMAC)
• Password is the master password from which a derived key is generated
• Salt is a sequence of bits, known as a cryptographic salt
• c is the number of iterations desired
• dkLen is the desired bit-length of the derived key
• DK is the generated derived key.

For example, using:

• password: Hello
• PRF: PBKDF2WithHmacSHA512
• Salt: vQIHs71+xAa4lxK9J+VhfA==
• Iterations: 1,000
• Derived key length: 128 bytes

will generate the same derived key bytes (tlXeEf65TEWTW41acGi/4A==).
