...But that alone would've been too easy to hack. To prevent an attacker from forging the keys by generating a new prefix: the hash latch doesn't output the keys in the plaintext. Instead, it encrypts the key and outputs the ciphertext. That means that instead of giving you the actual key, it gives you a safe containing the key. This approach allows the hash latch to protect itself from forged keys and also enables you to put the same key into multiple safes without the recipients of these safes knowing they have the same key (even if they compare their ciphertexts). ...

AVR128DA /Atmega128 microcontroller based open source EID smartcard with RSA (512-2048) and ECC (prime192v1, prime256v1, secp384r1, secp521r1 and secp256k1) support. Compatible with MyEID card from Aventra. Supported in windows and linux by opensc package. Allow about 64KiB space for keys/certificates. PKCS#15 structure supported. USB token with CCID interface based on xmega128a4u with same features as card. High speed AVR multiple precision arithmetic: squaring, multiplication, exponentiation.

v1pad is a command-line tool that encrypts and decrypts files using one-time-pad encryption. v1pad uses a virtual pad, meaning that the one-time pad is generated dynamically based on user input instead of being stored in a file. The name v1pad is an abbreviation for Virtual One-Time Pad.

MOTET is a tiny, fast super-encipherment application written in C, featuring the new CSPRNG/stream ciphers MOTE and BEDBUG in each of their three variants, as well as the "gold standard" among ciphers, ISAAC. MOTET brings multiple levels of encryption, including a ciphertext-hash, a Vigenere mixing function, a choice of Caesar MOD or Caesar MIX ciphering on the primary key-stream, plus a deeply scrambled "outer shell" as a final super-encryption stage. A unique nonce IV guarantees that each ciphertext will differ radically from every other, even on the same message and identical key.

Set of tools needed to setup and maintain encrypted partitions under unix systems (initially linux). Especially helpfull when doing root device encryption. Features xml configuration, multiple users, usb "tokens" (usb mass storage) and key hierarchy.

Primary Cryption -- a data protection tool. Uses thousands of prime numbers as sources of pseudorandom digits for performing extremely strong encryption of multiple files. The key is an average ordinary file; its content is used to select the primes.
