MD4 message digest algorithm (hash function)

Warning

MD4 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Defines

MBEDTLS_ERR_MD4_HW_ACCEL_FAILED

MD4 hardware accelerator failed

Functions

void mbedtls_md4_init(mbedtls_md4_context *ctx)

Initialize MD4 context.

Warning

MD4 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters

ctx – MD4 context to be initialized

void mbedtls_md4_free(mbedtls_md4_context *ctx)

Clear MD4 context.

Warning

MD4 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters

ctx – MD4 context to be cleared

void mbedtls_md4_clone(mbedtls_md4_context *dst, const mbedtls_md4_context *src)

Clone (the state of) an MD4 context.

Warning

MD4 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_md4_starts_ret(mbedtls_md4_context *ctx)

MD4 context setup.

Warning

MD4 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_md4_update_ret(mbedtls_md4_context *ctx, const unsigned char *input, size_t ilen)

MD4 process buffer.

Warning

MD4 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters
  • ctx – MD4 context

  • input – buffer holding the data

  • ilen – length of the input data

Returns

0 if successful

int mbedtls_md4_finish_ret(mbedtls_md4_context *ctx, unsigned char output[16])

MD4 final digest.

Warning

MD4 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters
  • ctx – MD4 context

  • output – MD4 checksum result

Returns

0 if successful

int mbedtls_internal_md4_process(mbedtls_md4_context *ctx, const unsigned char data[64])

MD4 process data block (internal use only)

Warning

MD4 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters
  • ctx – MD4 context

  • data – buffer holding one block of data

Returns

0 if successful

int mbedtls_md4_ret(const unsigned char *input, size_t ilen, unsigned char output[16])

Output = MD4( input buffer )

Warning

MD4 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 – MD4 checksum result

Returns

0 if successful

int mbedtls_md4_self_test(int verbose)

Checkup routine.

Warning

MD4 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
