These functions generate key fingerprints for public keys, certificates and key data. The fingerprints are created so that they they will be identical for a key and its corresponding certificate.
Note that in the case of certificates these are not fingerprints of the actual certificate data, but rather of the public key contained in a certificate.
These fingerprints are created using the subjectPublicKeyInfo ASN.1 structure.
guchar * gcr_fingerprint_from_attributes (GckAttributes *attrs,GChecksumType checksum_type,gsize *n_fingerprint);
Create a key fingerprint for a certificate, public key or private key.
Note that this is not a fingerprint of certificate data, which you would
use gcr_certificate_get_fingerprint() for.
attrs |
attributes for key or certificate |
|
checksum_type |
the type of fingerprint to create |
|
n_fingerprint |
the length of fingerprint returned |
the
fingerprint or NULL if the input was invalid.
[transfer full][allow-none][array length=n_fingerprint]
guchar * gcr_fingerprint_from_subject_public_key_info (const guchar *key_info,gsize n_key_info,GChecksumType checksum_type,gsize *n_fingerprint);
Create a key fingerprint for a DER encoded subjectPublicKeyInfo.
key_info |
DER encoded subjectPublicKeyInfo structure. |
[array length=n_key_info] |
n_key_info |
length of DER encoded structure |
|
checksum_type |
the type of fingerprint to create |
|
n_fingerprint |
the length of fingerprint returned |
the
fingerprint or NULL if the input was invalid.
