The IV is currently derived from the password and salt.
It should be generated randomly (via RNGCryptoServiceProvider).

Implement a AsymmetricCipher using the Cipher base class.

Implement support for HMACs to provide another way for message authentication, integrity checking and everything else provided by signatures.

Hint: Possible interface to support is  System.Security.Cryptography.KeyedHashAlgorithm

Add support for the symmetrical one-time pad.

Check performance and find bottlenecks

The ECDiffieHellmanCipher only supports hash based key derivations.
TLS and HMAC support should be implemented.

Implement different factories, each providing different levels of secure ciphers.

Implement (different?) shuffle algorithms for shuffling collections.

At least Fisher-Yates shuffle.

When passing a reference to another cipher (AesManaged or similar), one should be able to specify if the reference shall also be disposed.

There is currently no support for handling keys like the AsymmetricCiphers ToEncryptedXmlString/FromEncryptedXmlString methods provide.

The "packer" should be able to en/decrypt the symmetric key using public and private key cryptography.

The current GenericHasher creates a new instance every time it is used. This is not great performance-wise.

Implement a new class for hashing, likewise SymmetricCipher.

Cipha lacks support of ECDiffieHellman key exchange

Add support to en/decrypt/process large amount of data asynchronously.
