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
