Function esp_idf_sys::mbedtls_sha1_finish

pub unsafe extern "C" fn mbedtls_sha1_finish(
    ctx: *mut mbedtls_sha1_context,
    output: *mut c_uchar
) -> c_int

\brief This function finishes the SHA-1 operation, and writes the result to the output buffer.

\warning SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

\param ctx The SHA-1 context to use. This must be initialized and have a hash operation started. \param output The SHA-1 checksum result. This must be a writable buffer of length \c 20 Bytes.

\return \c 0 on success. \return A negative error code on failure.
