Key lengths are typically 128 or 256 bits, depending on the security criteria. The key length is even longer; the recommended RSA key size for asymmetric encryption is 2048 bits or greater.

WebPublic key cryptography, also known as asymmetric cryptography, uses two different but mathematically linked keys -- one public and one private. The public key can be shared with everyone, whereas the private key must be kept secret. RSA is a type of asymmetric encryption, which uses two different but linked keys. WebA key is a string of data that, when used in conjunction with a cryptographic algorithm, encrypts or decrypts messages. Data encrypted with the key will look like a random series of characters, but anyone with the right key can put it back into plaintext form. (A key can also be used to digitally sign data, not just for encryption.)
