object --+ | DerObject --+ | DerOctetString
Class to model a DER OCTET STRING.
An example of encoding is:
>>> from Crypto.Util.asn1 import DerOctetString >>> from binascii import hexlify, unhexlify >>> os_der = DerOctetString(b'\xaa') >>> os_der.payload += b'\xbb' >>> print hexlify(os_der.encode())
which will show 0402aabb, the DER encoding for the byte string b'\xAA\xBB'.
For decoding:
>>> s = unhexlify(b'0402aabb') >>> try: >>> os_der = DerOctetString() >>> os_der.decode(s) >>> print hexlify(os_der.payload) >>> except (ValueError, EOFError): >>> print "Not a valid DER OCTET STRING"
the output will be aabb.
