PBKDF2 key encoder for use in shell. Single, tiny binary. Written in Go.

gpbkdf2

Single-binary, tiny and fast shell application for encoding passwords using Password Based Key Deriviation Function 2 (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.

NOTE: gpbkdf2 has stable API, it is safe to use it in the scripts.

Usage

./gpbkdf2 --passphrase=my-secret-passphrase --salt=my-secret-salt --digest-algorithm=sha512 --digest-rounds=10000 --length=128
