Products that Use Twofish
This list is a compilation of encryption products that use the Twofish encryption algorithm. Counterpane has not verified that Twofish has been implemented properly, nor have we evaluated the security of these products. Readers are cautioned that there is more to creating a secure product than having a secure algorithm; for details read the essays Why Cryptography is Harder Than it Looks and Security Pitfalls in Cryptography. The listing of a product here is not an endorsement in any way. Some settling of contents may have occured during shipping. Keep off the grass.
