ROT-13
ROT-13 is a simple substitution cipher used to obfuscate Usenet posts. ROT-13 is not meant for use as a data encryption cipher.
ROT-13 is so named because every character is rotated 13 places.

- Substitution and Transposition Ciphers
Substitution and transposition ciphers are two categories of ciphers used in classical cryptography. Substitution and transposition differ in how chunks of the message are handled by the encryption process. Substitution ciphers Substitution ciphers encrypt plaintext by changing the plaintext one piece at a time. The Caesar Cipher was an early substitution cipher. In the Caesar [...]...
- XOR Encryption
The XOR encryption is a simple symmetric cipher that is used in many applications where security is not a defined requirement. The XOR Operator XOR (Exclusive OR) is a bitwise operator from binary mathematics. The six bitwise operators, as defined in the C programming language, are: Operation Symbol AND & Inclusive OR | Exclusive OR [...]...
- Plaintext and Ciphertext
Plaintext Plaintext, also known as cleartext, is usable data. It is data either before encryption or after successful decryption. Ciphertext Ciphertext is encrypted data. Plaintext can not be deduced from properly encrypted ciphertext. Here is a brief message in ciphertext: pgAAADP1wJU8OtQgiOPV9b+EyS6Iz6acuGAKrm1 GEcI4eJJolT68cOb1H/o/PxZ8 nYIs0UupT+0= =7mu0 Encryption and Decryption Encryption is the process of turning plaintext into [...]...
- Chosen Plaintext Attack
A chosen plaintext attack is an attack where the cryptanalyst is able to define his own plaintext, feed it into the cipher, and analyze the resulting ciphertext. Mounting a chosen plaintext attack requires the cryptanalyst to be able to send data of his choice into the device which is doing the encryption, and it requires [...]...
- Known Ciphertext Attack
A known ciphertext attack is an an attack where the cryptanalyst only has access to encrypted ciphertext. A known ciphertext attack is the easiest of the common cryptanalysis attacks to mount, because is requires the least amount of control over the encryption device. Conversely, the known ciphertext is the most difficult of the common methods [...]...
