Asymmetric Cryptography: Under this system, a pair of keys is used to encrypt and decrypt information. A public key is used for encryption and a private key is used for decryption. The public key and the private key are different. Next, copy the encrypted text you received into the "Enter the text to be decoded here" field and click on "DECRYPT TEXT". The original text will be displayed in the corresponding field. SIGN AND VERIFY A MESSAGE :In the "Sign/Verify pgp message" section, paste your private key into the "Enter the private key here" field and enter your passphrase. Symmetric encryption, also known as a shared key or private key algorithm, uses the same key for encryption and decryption. Symmetric key ciphers are considered less expensive to produce and do not take as much computing power to encrypt and decrypt, meaning there is less of delay in decoding the data. Cryptography is the practice of securing useful information while transmitting from one computer to another or storing data on a computer.
