Function

Gcrfingerprint_from_subject_public_key_info

Declaration [src]

guchar*
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.

Parameters

`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`.
