- Update to 1.0.4
* Support for AES256-GCM has been added. This requires a CPU with
the aesni and pclmul extensions, and is accessible via the
crypto_aead_aes256gcm_*() functions.
* ChaCha20 with an extended (96 bit) nonce and a 32-bit counter has
been implemented as crypto_stream_chacha20_ietf(),
crypto_stream_chacha20_ietf_xor() and crypto_stream_chacha20_ietf_xor_ic().
An IETF-compatible version of ChaCha20Poly1305 is available as
crypto_aead_chacha20poly1305_ietf_npubbytes(),
crypto_aead_chacha20poly1305_ietf_encrypt() and
crypto_aead_chacha20poly1305_ietf_decrypt().
* The sodium_increment() helper function has been added, to increment
an arbitrary large number (such as a nonce).
* The sodium_compare() helper function has been added, to compare
arbitrary large numbers (such as nonces, in order to prevent replay attacks).
