void mbedtls_sha512_clone(mbedtls_sha512_context *dst, const mbedtls_sha512_context *src)
This function clones the state of a SHA-512 context.
void mbedtls_sha512_init(mbedtls_sha512_context *ctx)
This function initializes a SHA-512 context.
#define MBEDTLS_PRIVATE(member)
int mbedtls_sha512_update(mbedtls_sha512_context *ctx, const unsigned char *input, size_t ilen)
This function feeds an input buffer into an ongoing SHA-512 checksum calculation. ...
int mbedtls_sha512_finish(mbedtls_sha512_context *ctx, unsigned char *output)
This function finishes the SHA-512 operation, and writes the result to the output buffer...
Macro wrapper for struct's memebrs.
int mbedtls_sha512_self_test(int verbose)
The SHA-384 or SHA-512 checkup routine.
Build-time configuration info.
int mbedtls_internal_sha512_process(mbedtls_sha512_context *ctx, const unsigned char data[128])
This function processes a single data block within the ongoing SHA-512 computation. This function is for internal use only.
int mbedtls_sha512(const unsigned char *input, size_t ilen, unsigned char *output, int is384)
This function calculates the SHA-512 or SHA-384 checksum of a buffer.
void mbedtls_sha512_free(mbedtls_sha512_context *ctx)
This function clears a SHA-512 context.
int mbedtls_sha512_starts(mbedtls_sha512_context *ctx, int is384)
This function starts a SHA-384 or SHA-512 checksum calculation.
