 totse.com | The Blowfish Cipher   (Site not responding. Last check: )
Almost all block ciphers since Lucifer [5,21] are Feistel ciphers, and all have a flat keyspace (with the possible exception of a few weak keys).
Implementations of Blowfish that require the fastest speeds should unroll the loop and ensure that all subkeys are stored in cache.
Blowfish is easy to scale up to a 128-bit block, and down to smaller block sizes.

The Blowfish cipher is extremely strong, is completely free, and currently does not have any public VHDL or hardware implementation of any sort readily available anywhere.
Blowfish was designed in 1993 by Bruce Schneier as a fast, free alternative to existing encryption algorithms.
The Blowfish algorithm is block cipher consisting of a standard Fiestel network with 16 rounds, plus some initial and final encryption functions.

 Cryptography Tutorials - Herong's Tutorial Notes - Cipher - Blowfish Algorithm
Usually, a block cipher encrypts a block of clear text into a block of cipher text of the same length.
In this case, a block cipher can be viewed as a simple substitute cipher with character size equal to the block size.
Blowfish was developed by Bruce Schneier in 1993.

 Block Ciphers
The general operation of all block ciphers is the same - a given number of bits of plaintext (a block) is encrypted into a block of ciphertext of the same size.
Cipher feedback mode (CFB) differs from OFB in that the ciphertext (after the XOR step) is fed back rather than the output of the block cipher (before the XOR step).
Blowfish, documented here is another unpatented Feistel algorithm using a variable length key.

 Blowfish Encryption Algorithm
Almost all block ciphers since Lucifer [5,21] are Feistel ciphers, and all have a flat keyspace (with the possible exception of a few weak keys).
The underlying philosophy behind Blowfish is that simplicity of design yields an algorithm that is both easier to understand and easier to implement.

Additionnaly maintaining the very SAME SPEED of the original cipher, or a lower reducing the number of loops allowed by sinergetic action from text due to the increased block size.
Blowfish was choosen because of its huge password-space, versatility, and wide array of Non-defined P-Boxes.
Note: Since even week cipher get much stronger with the DNA method the analysis of the cipher MUST be made without envolvement of it to obtain a accurate evaluation of the basic cipher.

 Blowfish encrypt and decrypt online
Blowfish is capable of strong encryption and can use key sizes up to 56 bytes (a 448 bit key).
Because Blowfish creates blocks of 8 byte encrypted output, the output is also padded and unpadded to multiples of 8 bytes.
To Decrypt, select "Decrypt", paste the ASCII-Hex encrypted text in in the "Blowfish Plain" box and make sure the password is the same as the one you used to Encrypt.

In cryptography, Blowfish is a keyed, symmetric block cipher, designed in 1993 by Bruce Schneier and included in a large number of cipher suites and encryption products.
While no effective cryptanalysis of Blowfish has been found to date, more attention is now given to block ciphers with a larger block size, such as AES or Twofish.

 The Blowfish Encryption Algorithm with Java Source Code (Cryptography)
Blowfish is a block cipher that encrypts data in 8-byte blocks.
Because the Blowfish cipher engine is designed to handle two 32-bit blocks, this method's purpose is to transform on entry and exit the data to/from 32-bit blocks; ie.
The input becomes two 32-bit blocks as Left and Right halves onto which the Blowfish cipher function is applied ROUNDS times in reverse order to that of the encryption.

The blowfish cipher is a two-way cipher meaning the original string that was encrypted can be retrieved.
The way that this version of the blowfish cipher is enrcypted it is safe to use as a form value.
The blowfish cipher is a two way cipher meaning that given the secret key you can de-cipher what the original string is. For one-way encryption look at methods dealing with the Sha alogrithm.

 Crypt::CBC
First it needs the name of the block cipher algorithm that will encrypt or decrypt the data in blocks of fixed length known as the cipher's "blocksize." Second, it needs an encryption/decryption key to pass to the block cipher.
To take full advantage of a given block cipher, the length of the passphrase should be at least equal to the cipher's blocksize.
These read-only methods return the identity of the chosen block cipher algorithm, padding method, key and block size of the chosen block cipher, and whether PCBC chaining is in effect.

Since the job of a cipher is to create highly randomized data there will not be much a compression algorithm could do with it.
Cipher's, AlgorithmParameters, and SecureRandom objects are not thread safe.

 Cryptit - The Blowfish based encryptiuon freeware
It will normally read plaintext or Cipher text from one file and write its conjugate to another, but it will, optionally, read plaintext from the keyboard or write it to the screen, or encrypt file in-situ, overlaying the plaintext with the cipher text.
If, however, the cipher text is typed-in from the keyboard (/ek flag), (and if only the operator can possibly observe the screen), the program can be set to echo "in clear", by specifying the /c(learecho) flag.
Technically, CRYPTIT is a 64-bit block cipher (Blowfish) implemented in Cipher Block Chaining (CBC) mode, using an execution-specific random Initialization Vector (IV), and a trailer in which a count of random bytes overcomes a possible short-block at the end of the plaintext.
