Key Fingerprints

Key Fingerprints — Fingerprints for public and private keys

Description

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.

Functions

gcr_fingerprint_from_attributes ()

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.

Parameters

attrs

attributes for key or certificate

 

checksum_type

the type of fingerprint to create

 

n_fingerprint

the length of fingerprint returned

 

Returns

the fingerprint or NULL if the input was invalid.

gcr_fingerprint_from_subject_public_key_info ()

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.

Parameters

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

 

Returns

the fingerprint or NULL if the input was invalid.
