NetLib Encryptionizer supports AES 128/256 in CBC, ECB and CTR modes for file and folder encryption on the Windows platform. Pidgin (software), has a plugin that allows for AES Encryption; Javascrypt [8] Free open-source text encryption tool runs entirely in web browser, send encrypted text over insecure e-mail or fax machine.
A simple illustration of public-key cryptography, one of the most widely used forms of encryption. In cryptography, encryption is the process of transforming (more specifically, encoding) information in a way that, ideally, only authorized parties can decode. This process converts the original representation of the information, known as ...
Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it. This process prevents the loss of sensitive information via hacking. Decryption, the inverse of encryption, is the process of turning ciphertext into ...
ROT13 (Rotate13, " rotate by 13 places ", sometimes hyphenated ROT-13) is a simple letter substitution cipher that replaces a letter with the 13th letter after it in the Latin alphabet. ROT13 is a special case of the Caesar cipher which was developed in ancient Rome. Because there are 26 letters (2×13) in the basic Latin alphabet, ROT13 is its ...
Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity). Implementation. HMAC - MD5.
In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.
Tiny Encryption Algorithm. TEA suffers from equivalent keys (see text; Kelsey et al., 1996) and can be broken using a related-key attack requiring 2 23 chosen plaintexts and a time complexity of 2 32. [2] The best structural cryptanalysis of TEA in the standard single secret key setting is the zero-correlation cryptanalysis breaking 21 rounds ...
Format-preserving encryption. In cryptography, format-preserving encryption (FPE), refers to encrypting in such a way that the output (the ciphertext) is in the same format as the input (the plaintext). The meaning of "format" varies. Typically only finite sets of characters are used; numeric, alphabetic or alphanumeric.
