Expand description

crypto_pwhash_scryptsalsa208sha256, a particular combination of Scrypt, Salsa20/8 and SHA-256

Structs

HashedPasswordis a password verifier generated from a password

MemLimit represents the maximum amount of RAM that the functions in this module will use, in bytes.

OpsLimit represents the maximum number of computations to perform when using the functions in this module.

Salt used for password hashing

Number of bytes in a HashedPassword.

Safe base line for MemLimit for interactive password hashing.

MemLimit for highly sensitive data.

Safe base line for OpsLimit for interactive password hashing.

OpsLimit for highly sensitive data.

Number of bytes in a Salt.

All HashedPasswords start with this string.

The derive_key() function derives a key from a password and a Salt

gen_salt() randombly generates a new Salt for key derivation

The pwhash() returns a HashedPassword which includes:

pwhash_verify() verifies that the password str_ is a valid password verification string (as generated by pwhash()) for passwd
