WebFeb 1, 2024 · Modern cryptography (computer-based encryption) In the early 1970s: IBM formed a 'crypto group,' which designed a block cypher to protect its customers' data. In 1973, the US adopted it as a national standard - the Data Encryption Standard, or DES. It remained in use until it cracked in 1997.

WebThese algorithms change the data into illegible, difficult-to-understand form. These particular cryptographic methods convert plaintext into cyphertext, which needs a key to be decoded, from the input plaintext. The cryptography algorithm also creates this key. The encryption of a given plaintext will always be the same, as will the decryption key.
WebNov 8, 2024 · Cryptographic operations in .NET Core and .NET 5+ are done by operating system (OS) libraries. This dependency has advantages: .NET apps benefit from OS reliability.
