sodium_crypto_stream_xchacha20_xor — Encrypts a message using a nonce and a secret key (no authentication)
Encrypts a message
using a nonce
and a secret key
(no authentication).
This encryption is unauthenticated, and does not prevent chosen-ciphertext attacks. Make sure to combine the ciphertext with a Message Authentication Code, for example with sodium_crypto_aead_xchacha20poly1305_ietf_encrypt() function, or sodium_crypto_auth().
message
The message to encrypt.
nonce
24-byte nonce.
key
Key, possibly generated from sodium_crypto_stream_xchacha20_keygen().
Encrypted message.
