|
|
|
The functions d2i_X509_SIG() and i2d_X509_SIG() decode and encode an
|
|
|
|
|
X509_SIG structure which is equivalent to the B<DigestInfo> structure
|
|
|
|
|
defined in PKCS#1 and PKCS#7.

|
|
|
|
2016-03-10 15:04:46 +00:00
|
|
|
Otherwise they behave in a similar way to d2i_X509() and i2d_X509()

|
|
|
X509_SIG_get0() returns pointers to the algorithm identifier and digest
|
|
|
|
|
value in B<sig>. These values can then be examined or initialised.
