void mbedtls_sha1_clone(mbedtls_sha1_context *dst, const mbedtls_sha1_context *src)
This function clones the state of a SHA-1 context.
int mbedtls_sha1_self_test(int verbose)
The SHA-1 checkup routine.
int mbedtls_sha1_finish(mbedtls_sha1_context *ctx, unsigned char output[20])
This function finishes the SHA-1 operation, and writes the result to the output buffer.
