Crate safe_crypto

This is a convenience library providing abstractions for cryptographic functions required by other SAFE Network libraries.

Structs

PublicEncryptKey	The public key used encrypt data that can only be decrypted by the corresponding secret key, which is represented by SecretEncryptKey. Use gen_encrypt_keypair() to generate a public and secret key pair.
PublicSignKey	Public signing key used to verify that the signature appended to a message was actually issued by the creator of the public key.
SecretEncryptKey	Reference counted secret encryption key used to decrypt data previously encrypted with PublicEncryptKey. Use gen_encrypt_keypair() to generate a public and secret key pair.
SecretSignKey	Reference counted secret signing key used to verify signatures previously signed with PublicSignKey.
SharedSecretKey	Precomputed shared secret key.
Signature	Detached signature.
SymmetricKey	Secret key for authenticated symmetric encryption.

Enums

Error

This error is returned if encryption or decryption fails. The encryption failure is rare and mostly connected to serialisation failures. Decryption can fail because of invalid keys, invalid data, or deserialisation failures.

Constants

PUBLIC_ENCRYPT_KEY_BYTES	Public encryption key length in bytes.
PUBLIC_SIGN_KEY_BYTES	Public signing key length in bytes.
SECRET_ENCRYPT_KEY_BYTES	Secret encryption key length in bytes.
SECRET_SIGN_KEY_BYTES	Secret signing key length in bytes.
SHARED_SECRET_KEY_BYTES	Shared secret key length in bytes.
SIGNATURE_BYTES	Cryptographic signature length in bytes.
SYMMETRIC_KEY_BYTES	Symmetric key length in bytes.

Functions

gen_encrypt_keypair	Randomly generates a secret key and a corresponding public key.
gen_sign_keypair	Construct random public and secret signing key pair.
hash	Produces a 256-bit crypto hash out of the provided data.
init	Initialise safe_crypto including the random number generator for the key generation functions.
