Ciphers are strategies of encoding info to make it unintelligible to unauthorized events. They’ve been used for hundreds of years to guard delicate info, corresponding to navy secrets and techniques, diplomatic communications, and private letters.
Ciphers could be created utilizing a wide range of strategies, together with substitution, transposition, and encryption algorithms. Substitution ciphers exchange every letter of the plaintext with a distinct letter, image, or quantity. Transposition ciphers rearrange the order of the letters within the plaintext. Encryption algorithms use advanced mathematical operations to scramble the plaintext.
