...The minified version of the library is under 6.4KB compressed, and yet it posts impressive speed results. SJCL is secure. It uses the industry-standard AES algorithm at 128, 192 or 256 bits; the SHA256 hash function; the HMAC authentication code; the PBKDF2 password strengthener; and the CCM and OCB authenticated-encryption modes. Just as importantly, the default parameters are sensible: SJCL strengthens your passwords by a factor of 1000 and salts them to protect against rainbow tables, and it authenticates every message it sends to prevent it from being modified. ...

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.

...To achieve long-term data secrecy, Azrar differs from other approaches in terms of not to rely on effective computational deficiencies. It combines a one-time pad with a stream cipher method using the strong cryptographic hash function (family) Skein. Azrar fulfills business requirements for secure data transfer and supports several operating systems natively. It does not use a runtime environment.

My first attempt at a one-way hashing class/algoritm, built as a python class. It produces variable length hash from a message block of the size you want. The resulting hash will be ~2x the message block in size, and should provide for at least as many bits of security as the block itself. I updated this, with a different hash than original, since I found a potential collision on some blocks, not but specific to that challenge. To further correct this, I modified the padding when it's...
