Blowfish is a variable-length, symmetric, 64-bit block cipher. Designed by Bruce Schneier in 1993 as a "general-purpose algorithm," it was intended to provide a fast, free, drop-in alternative to the ...

Researchers have found a new way to recover and decrypt authentication cookies from 3DES and Blowfish protected traffic. In response, OpenSSL is expected to deprecate 3DES’ designation from high to ...

Many embedded systems depend on obscurity to achieve security. We often design systems to download unsigned or unencrypted firmware upgrades or store unencrypted user data, a practice we justify ...

Now, that's not a wonderful piece of code, filled with incredible meta-programming snippets. But it's a piece of code that's usable and - more importantly - that can be modified to suit your needs. So ...

A longstanding bug that was recently found in the crypt_blowfish password hashing library highlights the problems that can occur when a bug is found in a widely used low-level library. Because ...

A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...

Of course, firmware upgrades and data logs are seldom exactly 64 bits in length. To encrypt long strings of data using Blowfish, carve the message up into 64-bit blocks, encrypt each block and save ...
