ASN.1 type classes for various algorithms using in various aspects of public
key cryptography. Exports the following items:
- AlgorithmIdentifier()
- DigestAlgorithm()
- DigestInfo()
- DSASignature()
- EncryptionAlgorithm()
- HmacAlgorithm()
- KdfAlgorithm()
- Pkcs5MacAlgorithm()
- SignedDigestAlgorithm()
Other type classes are defined that help compose the types listed above.

Returns the key length to pass to the cipher/kdf. The PKCS#5 spec does
not specify a way to store the RC5 key length, however this tends not
to be a problem since OpenSSL does not support RC5 in PKCS#8 and OS X
does not provide an RC5 cipher for use in the Security Transforms
library.

Returns the name of the symmetric encryption cipher to use. The key
length can be retrieved via the .key_length property to disabiguate
between different variations of TripleDES, AES, and the RC* ciphers.

Returns the byte string of the initialization vector for the encryption
scheme. Only the PBES2 stores the IV in the params. For PBES1, the IV
is derived from the KDF and this property will return None.
