    Constants

    KEY_SIZE ¶
    Source

    KEY_SIZE :: chacha20.KEY_SIZE
     

    KEY_SIZE is the chacha20poly1305 key size in bytes.

    NONCE_SIZE ¶
    Source

    NONCE_SIZE :: chacha20.NONCE_SIZE
     

    NONCE_SIZE is the chacha20poly1305 nonce size in bytes.

    TAG_SIZE ¶
    Source

    TAG_SIZE :: poly1305.TAG_SIZE
     

    TAG_SIZE is the chacha20poly1305 tag size in bytes.

    Procedures

    decrypt ¶
    Source

    decrypt :: proc(
	plaintext, tag, key, nonce, aad, 
	ciphertext:                      []u8, 
) -> bool {…}
     

    decrypt authenticates the aad and ciphertext, and decrypts the ciphertext, with the provided key, nonce, and tag, and stores the output in plaintext, returning true iff the authentication was successful.

    If authentication fails, the destination plaintext buffer will be zeroed.

    encrypt ¶
    Source

    encrypt :: proc(
	ciphertext, tag, key, nonce, aad, 
	plaintext:                        []u8, 
) {…}
     

    encrypt encrypts the plaintext and authenticates the aad and ciphertext, with the provided key and nonce, stores the output in ciphertext and tag.
