1 40-bit encryption
A low level of encryption that uses a 40-bit key to scramble the contents of a file or data packet to make the data unreadable without the decryption key. -
2 128-bit encryption
A high level of encryption that uses a 128-bit key to scramble the contents of a file or data packet to make the data unreadable without the decryption key. -
3 secret key encryption
"An encryption algorithm that requires the same secret key to be used for both encryption and decryption. Because of its speed, symmetric encryption is typically used when a message sender needs to encrypt large amounts of data." -
4 symmetric encryption
"An encryption algorithm that requires the same secret key to be used for both encryption and decryption. Because of its speed, symmetric encryption is typically used when a message sender needs to encrypt large amounts of data." -
5 public key algorithm
"An asymmetric cipher that uses two keys, one for encryption, the public key, and the other for decryption, the private key. As implied by the key names, the public key used to encode plaintext can be made available to anyone. However, the private key must remain secret. Only the private key can decrypt the ciphertext. The public key algorithm used in this process is slow (on the order of 1,000 times slower than symmetric algorithms), and is typically used to encrypt session keys or digitally sign a message."
