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)

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
