Silence is a free, open-source messaging encryption software, based on a fork from TextSecure software. It allows the secure exchange of SMS and MMS-type messages with other Silence or TextSecure users. The program allows message encryption and identity verification between correspondents by comparing the fingerprint of the encryption keys. [1] [2]
The Zimmermann Telegram (as it was sent from Washington to Mexico) encrypted as ciphertext. KGB ciphertext found in a hollow nickel in Brooklyn in 1953. In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher. [1]
Historically, various forms of encryption have been used to aid in cryptography. Early encryption techniques were often used in military messaging. Since then, new techniques have emerged and become commonplace in all areas of modern computing. [1] Modern encryption schemes use the concepts of public-key and symmetric-key. [1]
Here are two text messaging apps that use end-to-end encryption. Once you've downloaded either of these apps to your smartphone, you can also link them to your desktop computers.
A format of one-time pad used by the U.S. National Security Agency, code named DIANA.The table on the right is an aid for converting between plaintext and ciphertext using the characters at left as the key.
Substitution Ciphers and the Aristocrat Cipher are still used in many ways today including storage encryption, password encryption, cyber security, etc. The most common of these is data encryption, where using the Encryption Algorithms you convert plaintext to ciphertext, allowing your data to be stored without easy exfiltration.

VeraCrypt is a free and open-source utility for on-the-fly encryption (OTFE). [5] The software can create a virtual encrypted disk that works just like a regular disk but within a file. It can also encrypt a partition [6] or (in Windows) the entire storage device with pre-boot authentication. [7] VeraCrypt is a fork of the discontinued ...
In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code.
