11## Yleistä
22
33- [DCPcrypt](http://www.cityinthesky.co.uk/cryptography.html) on kokoelma salauskomponentteja Lazarukseen.
44- DCPcrypt:n tausta ideana on "vedä ja pudota" mikä tahansa algoritmi ja jonka voit korvata sen vähäisillä muutoksilla toiseksi. Tähän päämäärään on pyritty erottamalla salaus ja tiivistealgoritmit omiin kantaluokkiin: TDCP_cipher salausalgoritmeille ja TDCP_hash tiivistealgoritmeille.

5145Please note that an appreciation of the basic principles of encryption/decryption and key management is needed to ensure the correct usage of the ciphers implemented within this package. A good introduction on this subject is provided by Bruce Schneier's "Applied Cryptography" (ISBN: 0-471-11709-9) also see the NIST publication SP800-38A for information on the block cipher chaining modes.

5347- Ciphers - the basic building block of DCPcrypt, the TDCP_cipher component.
5448- Block Ciphers - the base of all block ciphers, the TDCP_blockcipher component.
5549- Hashes - the base of all hash algorithms, the TDCP_hash component.
