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
