Encrypt a message with a password:

Show the raw encrypted data and details about the encryption algorithm used:

Decrypt with the password to get back the message:

Generate a secret key:

Encrypt 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:

Byte arrays are encrypted literally, making them more easily usable with external programs:

Encrypt a message and save the ciphertext to a file:

Read back the contents of the file as bytes:

Compare with the original ciphertext:

Delete the temporary file:

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:

The returned encrypted object stores all aspects of the encrypted result:

Extract the bytes in the ciphertext:

Extract the bytes in the initialization vector used for encryption:

Some block modes are more secure than others:

There is a noticeable repeating pattern when encrypting uniform data using ECB:

There is not with CBC:
