Expand description

Returns the UTF8 String representation of the DER encoded ASN.1 X.509 certificate extension data.

@param extension_data A pointer to the DER encoded ASN.1 X.509 certificate extension value being read. @param extension_len represents the length of the input buffer extension_data. @param out_data A pointer to the output buffer which will hold the UTF8 String representation of the DER encoded ASN.1 X.509 certificate extension data returned. @param out_len This value is both an input and output parameter and represents the length of the output buffer out_data. When used as an input parameter, the caller must use this parameter to convey the maximum length of out_data. When used as an output parameter, out_len holds the actual length of UTF8 String returned.
