Crypto.Saltine.Core.AEAD.XChaCha20Poly1305

Description

Secret-key authenticated encryption with additional data (AEAD): Crypto.Saltine.Core.AEAD.XChaCha20Poly1305

Nonces are long enough that randomly generated nonces have negligible risk of collision.

aead Source #

Arguments

:: Key 
-> Nonce 
-> ByteString

Message

-> ByteString

AAD

-> ByteString

Ciphertext

Encrypts a message. It is infeasible for an attacker to decrypt the message so long as the Nonce is never repeated.

aeadOpen Source #

Arguments

:: Key 
-> Nonce 
-> ByteString

Ciphertext

-> ByteString

AAD

-> Maybe ByteString

Message

Decrypts a message. Returns Nothing if the keys and message do not match.

aeadDetached Source #

Arguments

:: Key 
-> Nonce 
-> ByteString

Message

-> ByteString

AAD

-> (ByteString, ByteString)

Tag, Ciphertext

Encrypts a message. It is infeasible for an attacker to decrypt the message so long as the Nonce is never repeated.

aeadOpenDetached Source #

Arguments

:: Key 
-> Nonce 
-> ByteString

Tag

-> ByteString

Ciphertext

-> ByteString

AAD

-> Maybe ByteString

Message

Decrypts a message. Returns Nothing if the keys and message do not match.
