Cryha

Cryha is a Python toolkit for securing information into a data base; it lets hash passwords, and encrypt/decrypt personal information. It is ready for input of Unicode characters, and the schema is returned as Unicode. The text is stored according to this schema for a hash: separator, the hash function identifier, separator, the salt, separator, the hash output And this another for a Cipher text: separator, the cipher identifier, separator, the mode identifier, separator, the IV parameter, separator, the ciphertext The idea of the schema has been taken of Linux systems that store the hashed passwords so, using a $ as separator. The use of a schema let us to store the salt (for hash) and IV (for cipher) --which must be unique for each field--, together to the parameters that has been used to hashing/encrypting the text. The salt and IV parameters are obtained from a random String --using the PRNG of the operating system-- into a domain of 256 possible values for greater security.
