Encrypt a message with a password:

Decrypt with the same password to get back the message:

Generate a secret key:

Encrypt using the key:

Decrypt using the key:

Generate public and private keys:

Encrypt using the public key:

Decrypt using the private key:

Alternatively, encrypt using the private key:

Now decrypt using the public key:

Encrypt any expression:

Decrypt to get back the exact expression:

To decrypt byte array encrypted data, Decrypt needs to know details of the encryption algorithm used:

Create an EncryptedObject to specify the cipher, padding mode and format of the plaintext message:

Decrypt using the correct password or key:

Symmetric ciphers usually require an initialization vector for decryption:

Create an EncryptedObject to specify the cipher, block mode, initialization vector and format of the plaintext message:

Decrypt using the correct password or key:

Write simple cryptographic signing and verification functions:

Generate a pair of public and private keys:

Define an expression to sign:

Generate a signature:

Verify that the signature is authentic:

Verifying with another expression will fail:
