gcr_fingerprint_from_subject_public_key_info (
  const guchar* key_info,
  gsize n_key_info,
  GChecksumType checksum_type,
  gsize* n_fingerprint

Description [src]

Create a key fingerprint for a DER encoded subjectPublicKeyInfo. The fingerprint is created so that it will be identical for a key and its corresponding certificate.

Note that in the case of certificates this is not a fingerprint of the actual certificate data, but rather of the public key contained in a certificate.


key_info An array of guchar

DER encoded subjectPublicKeyInfo structure.

 The length of the array is specified in the n_key_info argument.
 The data is owned by the caller of the function.
n_key_info gsize

Length of DER encoded structure.

checksum_type GChecksumType

The type of fingerprint to create.

n_fingerprint gsize*

The length of fingerprint returned.

 The argument will be set by the function.

Return value

Returns: An array of guchar

The fingerprint or NULL if the input was invalid.

 The length of the array is in the n_fingerprint argument.
 The caller of the function takes ownership of the data, and is responsible for freeing it.
 The return value can be NULL.
