      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

    • DES (Data Encryption Standard)

      DES (Data Encryption Standard)

      DES (Data Encryption Standard) is a commonly used method for encrypting data using a secret or private key. The strength of the DES encryption standard was previously considered to be strong enough that the United States government placed restrictions on the export of the technology to other countries. Conceptually, there are more than 72 quadrillion

    • RSA (Rivest, Shamir, and Adleman)

      RSA (Rivest, Shamir, and Adleman)

      RSA, which stands for Rivest, Shamir, and Adleman, is a security algorithm used in digital cryptography. RSA differs from older symmetric algorithms because it has the ability of allowing digital signing as well as advanced encryption for online commerce systems and high-profile institutions. RSA was one of the first major advancements in digital cryptography but

      GnuPG Shell

      Everyone likes safety. The safety of confidential information is always of special concern. Therefore, information protection is a necessity and can be useful to companies and individuals who care about their intellectual property’s confidentiality. People who want their e-mails kept confidential and their e-mail attachments readable only to the intended recipient can appreciate information protection.

    • PKI Authorities

      PKI Authorities

      PKI Authorities consists of three different authorities that essentially make up a PKI system. These are the Registration Authority, Certification Authority and Certificate Directory. Registration Authority The jobs of the Registration Authority are to processes user requests, confirm their identities, and induct them into the user database. Certification Authority The tasks of a Certification Authority

    • Known Plaintext Attack

      Known Plaintext Attack

      In cryptography, the known plaintext attack, or KPA, is an attack based on having samples of both the plaintext and corresponding encrypted or ciphertext for that information available. This information is used to conduct an analysis of the data in order to determine the secret key used to encrypt and decrypt the information. Historical ciphers
