The DNA Decrypter is a machine added by Advanced Genetics. It is used to decrypt Helixes (Encrypted). It requires power to function, and must be either Redstone Flux (RF), Energy Units (EU), or power directly from Advanced Genetics' Combustion Generator. Decrypting a Helix is a slow process that requires a huge amount of power to complete.
The Helix (Decrypted) is then to be placed in a DNA Splitter.
