Module scrypt

The scrypt password hashing function.

scrypt was originally proposed in Stronger Key Derivation via Sequential Memory-Hard Functions and standardized in RFC 7914.

A note on terminology: scrypt is technically a key derivation function, and its output is thus technically a key. However, we expose it here only for the purposes of password verification, and thus we use the term “hash” to refer to its output.

Structs

• ScryptHash
  The output of the scrypt password hashing function.

• SCRYPT_SALT_LEN
  The length of an scrypt salt.

Functions

• scrypt_generate
  Generates an scrypt hash for the given password.
• scrypt_verify
  Verifies a password against an scrypt hash.
