Module bdrck::crypto::digest

digest defines an API for computing cryptographically secure digests of data.

Structs

Digest

A digest is a cryptographic hash of some arbitrary input data, with the goal of identifying it or detecting changes with high probability.

Salt

A salt is an arbitrary byte sequence which is used for password-based key derivation.

Constants

DIGEST_BYTES

This module uses sha512, which produces 64 byte digests.

MEM_LIMIT_INTERACTIVE

Safe mem_limit base line for password-based key derivation, for interactive password hashing.

MEM_LIMIT_SENSITIVE

mem_limit for highly sensitive data.

OPS_LIMIT_INTERACTIVE

Safe ops_limit base line for password-based key derivation, for interactive password hashing.

OPS_LIMIT_SENSITIVE

ops_limit for highly sensitive data.

SALT_BYTES

scryptsalsa208sha256 uses 32 byte salts.

Functions

derive_key

Hash the given password using the given salt and ops limits, placing the result in the given buffer. Note that the length of “out” is mostly arbitrary.
