WebApr 9, 2024 · Public Key Cryptography Standards in Cyber Security 101. Cryptography is the art and science of making information unreadable. It “locks” away information so that you need a “key” to read it. This practice predates IT infrastructure by millennia, but it’s an integral part of contemporary IT and security strategy. WebCryptography is a collection of techniques for: concealing data transmitted over insecure channels validating message integrity and authenticity 2 Some cryptographic terms plaintext – a message or other data in readable form ciphertext – a message concealed for transmission or storage encryption – transforming plaintext into ciphertext
WebApr 12, 2024 · The methods we use to convert it into cypher-text is called encryption, and the set of rules or the equations we use to go convert cypher-text to plaintext are called decryption.
