Module sodiumoxide::crypto::pwhash::scryptsalsa208sha256

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

Structs

HashedPassword	HashedPasswordis a password verifier generated from a password
MemLimit	MemLimit represents the maximum amount of RAM that the functions in this module will use, in bytes.
OpsLimit	OpsLimit represents the maximum number of computations to perform when using the functions in this module.
Salt	Salt used for password hashing

Constants

HASHEDPASSWORDBYTES	Number of bytes in a HashedPassword.
MEMLIMIT_INTERACTIVE	Safe base line for MemLimit for interactive password hashing.
MEMLIMIT_SENSITIVE	MemLimit for highly sensitive data.
OPSLIMIT_INTERACTIVE	Safe base line for OpsLimit for interactive password hashing.
OPSLIMIT_SENSITIVE	OpsLimit for highly sensitive data.
SALTBYTES	Number of bytes in a Salt.
STRPREFIX	All HashedPasswords start with this string.

Functions

derive_key	The derive_key() function derives a key from a password and a Salt
derive_key_interactive	derive_key_interactive() is a shortcut function for derive_key() with interactive limits (i.e. using derive_key() with OPSLIMIT_INTERACTIVE and MEMLIMIT_INTERACTIVE)
derive_key_sensitive	derive_key_sensitive() is a shortcut function for derive_key() with sensitive limits (i.e. using derive_key() with OPSLIMIT_SENSITIVE and MEMLIMIT_SENSITIVE)
gen_salt	gen_salt() randombly generates a new Salt for key derivation
pwhash	The pwhash() returns a HashedPassword which includes:
pwhash_interactive	pwhash_interactive() is a shortcut function for pwhash() with interactive limits (i.e. using pwhash() with OPSLIMIT_INTERACTIVE and MEMLIMIT_INTERACTIVE)
pwhash_sensitive	pwhash_sensitive() is a shortcut function for pwhash() with sensitive limits (i.e. using pwhash() with OPSLIMIT_SENSITIVE and MEMLIMIT_SENSITIVE)
pwhash_verify	pwhash_verify() verifies that the password str_ is a valid password verification string (as generated by pwhash()) for passwd
