WebSymmetric encryption is the process of converting plaintext into ciphertext and vice versa using the same key. An encryption key is a random string of bits used to encrypt or decrypt data. It is, therefore, important that key is transferred between the sender and recipient using secure methods. RC4, RC5, RC6, IDEA, Blowfish, AES, DES and 3DES ... WebAsymmetric cryptography is typically used to authenticate data using digital signatures. A digital signature is a mathematical technique used to validate the authenticity and integrity of a message, software or digital document. It is the digital equivalent of a handwritten signature or stamped seal.
