NAME

pkc_get_key_data — Returns a public key

Synopsis

unsigned32 pkc_get_key_data(
keyinfo_t ∗ keyinfobase,
unsigned key_index,
unsigned char ∗∗ key_data,
size_t ∗ key_length);

Parameters

Input

keyinfobaseKey information for the principal, returned by pkc_retrieve_keyinfo(3sec). 

key_indexIndex (ranging from 0 to key_count - 1) of the key desired. 

Output

key_dataThe encoded public key. 

key_lengthLength of the key data returned. 

Description

pkc_get_key_data(3sec) extracts an encoded public key from a keyinfo_t structure.  key_index is the index of the key (ranging from 0 to key_count - 1). 

The returned key_data is encoded as an ASN.1 BER SubjectPublicKeyInfo object (as defined in X.509). 

The desired information is extracted by from the keyinfo_t structure, which must first be obtained by the caller by a call to the pkc_retrieve_keyinfo(3sec) routine. 

Upon successful return, key_data will contain PKC-allocated storage which must be released with pkc_free(3sec) when the application has finished with it. 

Return Values

pkc_s_success
Operation successfully completed.
