Usage

step crypto kdf <subcommand> [arguments] [global-flags] [subcommand-flags]

Description

step crypto kdf command group creates and verifies passwords using key derivation functions.

Examples

Derive a password using scrypt:

$ step crypto kdf hash
Enter password to hash: 
$scrypt$ln=15,r=8,p=1$3TCG+xs8HWSIHonnqTp6Xg$UI8CYfz6koUaRMjDWEFgujIxM63fYnAcc0HhpUryFn8

$ step crypto kdf hash --insecure password

Derive a password using bcrypt:

$ step crypto kdf hash --alg bcrypt
Enter password to hash: 
$2a$10$EgTYeokp/EhvlMpaDYX56O67M/Ve4JyTl9DHwailYYFOBT3COSTuy

$ step crypto kdf hash --alg bcrypt --insecure password

Derive a password using argon2i:

$ step crypto kdf hash --alg argon2i
Enter password to hash: 
$argon2i$v=19$m=32768,t=3,p=4$H0IxAhFFO7fOu5K2RYTxxA$ULEz/79vh3BtCcm7W/zRfJSpiEGULirrZ+PnHfspWKA

Derive a password using argon2id:

$ step crypto kdf hash --alg argon2id
Enter password to hash: 
$argon2id$v=19$m=65536,t=1,p=4$HDi5gI15NwJrKveh2AAa9Q$30haKRwwUe5I4WfkPZPGmhJKTRTO+98x+sVnHhOHdK8

Validate a hash:

$ step crypto kdf compare '$scrypt$ln=15,r=8,p=1$3TCG+xs8HWSIHonnqTp6Xg$UI8CYfz6koUaRMjDWEFgujIxM63fYnAcc0HhpUryFn8'
