MD5 message digest algorithm (hash function)

Warning

MD5 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Defines

MBEDTLS_ERR_MD5_HW_ACCEL_FAILED

MD5 hardware accelerator failed

Functions

void mbedtls_md5_init(mbedtls_md5_context *ctx)

Initialize MD5 context.

Warning

MD5 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters:

ctx – MD5 context to be initialized

void mbedtls_md5_free(mbedtls_md5_context *ctx)

Clear MD5 context.

Warning

MD5 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters:

ctx – MD5 context to be cleared

void mbedtls_md5_clone(mbedtls_md5_context *dst, const mbedtls_md5_context *src)

Clone (the state of) an MD5 context.

Warning

MD5 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters:
  • dst – The destination context

  • src – The context to be cloned

int mbedtls_md5_starts_ret(mbedtls_md5_context *ctx)

MD5 context setup.

Warning

MD5 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters:

ctx – context to be initialized

Returns:

0 if successful

int mbedtls_md5_update_ret(mbedtls_md5_context *ctx, const unsigned char *input, size_t ilen)

MD5 process buffer.

Warning

MD5 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters:
  • ctx – MD5 context

  • input – buffer holding the data

  • ilen – length of the input data

Returns:

0 if successful

int mbedtls_md5_finish_ret(mbedtls_md5_context *ctx, unsigned char output[16])

MD5 final digest.

Warning

MD5 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters:
  • ctx – MD5 context

  • output – MD5 checksum result

Returns:

0 if successful

int mbedtls_internal_md5_process(mbedtls_md5_context *ctx, const unsigned char data[64])

MD5 process data block (internal use only)

Warning

MD5 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters:
  • ctx – MD5 context

  • data – buffer holding one block of data

Returns:

0 if successful

int mbedtls_md5_ret(const unsigned char *input, size_t ilen, unsigned char output[16])

Output = MD5( input buffer )

Warning

MD5 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters:
  • input – buffer holding the data

  • ilen – length of the input data

  • output – MD5 checksum result

Returns:

0 if successful

int mbedtls_md5_self_test(int verbose)

Checkup routine.

Warning

MD5 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Returns:

0 if successful, or 1 if the test failed
