WebNov 3, 2024 · In the most basic sense, encryption means using “fancy math” and a set of instructions (algorithms) to disguise and protect data. These algorithms scramble plaintext data into an incomprehensible text known as ciphertext, which looks like gibberish without the use of a special key that decrypts it. To verify that data was signed by a particular party, you must have the following information: 1. The public key of the party that signed the data. 2. The digital signature. 3. The data that was signed. 4. The hash algorithm used by the signer.
