MD2 message digest algorithm (hash function)

Warning

MD2 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Defines

MBEDTLS_ERR_MD2_HW_ACCEL_FAILED

MD2 hardware accelerator failed

Functions

void mbedtls_md2_init(mbedtls_md2_context *ctx)

Initialize MD2 context.

Warning

MD2 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters

ctx – MD2 context to be initialized

void mbedtls_md2_free(mbedtls_md2_context *ctx)

Clear MD2 context.

Warning

MD2 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters

ctx – MD2 context to be cleared

void mbedtls_md2_clone(mbedtls_md2_context *dst, const mbedtls_md2_context *src)

Clone (the state of) an MD2 context.

Warning

MD2 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_md2_starts_ret(mbedtls_md2_context *ctx)

MD2 context setup.

Warning

MD2 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_md2_update_ret(mbedtls_md2_context *ctx, const unsigned char *input, size_t ilen)

MD2 process buffer.

Warning

MD2 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters
  • ctx – MD2 context

  • input – buffer holding the data

  • ilen – length of the input data

Returns

0 if successful

int mbedtls_md2_finish_ret(mbedtls_md2_context *ctx, unsigned char output[16])

MD2 final digest.

Warning

MD2 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters
  • ctx – MD2 context

  • output – MD2 checksum result

Returns

0 if successful

int mbedtls_internal_md2_process(mbedtls_md2_context *ctx)

MD2 process data block (internal use only)

Warning

MD2 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.

Parameters

ctx – MD2 context

Returns

0 if successful

int mbedtls_md2_ret(const unsigned char *input, size_t ilen, unsigned char output[16])

Output = MD2( input buffer )

Warning

MD2 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 – MD2 checksum result

int mbedtls_md2_self_test(int verbose)

Checkup routine.

Warning

MD2 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
