Module crypto

Expand description

Cryptographic primitives.

This module contains cryptographic primitives as defined and used by OpenPGP. It abstracts over the cryptographic library chosen at compile time. Most of the time, it will not be necessary to explicitly use types from this module directly, but they are used in the API (e.g. Password). Advanced users may use these primitives to provide custom extensions to OpenPGP.

§Common Operations

Converting a string to a Password: Use Password::from.
Create a session key: Use SessionKey::new.
Use secret keys: See the KeyPair example.

Modules§

ecdh: Elliptic-curve Diffie-Hellman.
hash: Cryptographic hash functions and hashing of OpenPGP data structures.
mem: Memory protection and encryption.
mpi: Multiprecision Integers.

Structs§

KeyPair: A cryptographic key pair.
Password: Holds a password.
SessionKey: Holds a session key.

Enums§

AEADAlgorithm: AEAD modes.
Curve: Elliptic curves used in OpenPGP.
HashAlgorithm: The OpenPGP hash algorithms as defined in Section 9.5 of RFC 9580.
PublicKeyAlgorithm: The OpenPGP public key algorithms as defined in Section 9.1 of RFC 9580.
S2K: String-to-Key (S2K) specifiers.
SymmetricAlgorithm: The symmetric-key algorithms as defined in Section 9.3 of RFC 9580.

Traits§

Decryptor: Decrypts a message.
Signer: Creates a signature.

Functions§

backend: Returns a short, human-readable description of the backend.
random: Fills the given buffer with random data.
