win32crypt.CryptDecodeObjectEx

object = CryptDecodeObjectEx(StructType, Encoded , Flags , CertEncodingType , DecodePara )

Decodes ASN encoded data

StructType : str/int

An OID identifying the type of data to be decoded, can be either str or int

Encoded : str

String or buffer containing ASN encoded data

Flags=0 : int

Encoding options, can be combination CRYPT_UNICODE_* constants. CRYPT_ENCODE_ALLOC_FLAG is added to flags..

CertEncodingType=X509_ASN_ENCODING combined with PKCS_7_ASN_ENCODING : int

Encoding types

DecodePara=None : object

Not supported, use only None
