This file contains ChaCha20 definitions and functions.
int mbedtls_chachapoly_finish(mbedtls_chachapoly_context *ctx, unsigned char mac[16])
This function finished the ChaCha20-Poly1305 operation and generates the MAC (authentication tag).
void mbedtls_chachapoly_init(mbedtls_chachapoly_context *ctx)
This function initializes the specified ChaCha20-Poly1305 context.
int mbedtls_chachapoly_starts(mbedtls_chachapoly_context *ctx, const unsigned char nonce[12], mbedtls_chachapoly_mode_t mode)
This function starts a ChaCha20-Poly1305 encryption or decryption operation.
int mbedtls_chachapoly_setkey(mbedtls_chachapoly_context *ctx, const unsigned char key[32])
This function sets the ChaCha20-Poly1305 symmetric encryption key.
int mbedtls_chachapoly_update(mbedtls_chachapoly_context *ctx, size_t len, const unsigned char *input, unsigned char *output)
Thus function feeds data to be encrypted or decrypted into an on-going ChaCha20-Poly1305 operation.
void mbedtls_chachapoly_free(mbedtls_chachapoly_context *ctx)
This function releases and clears the specified ChaCha20-Poly1305 context.
