Encrypt With Key
Purpose
Uses a specified encryption key to make text unreadable.
Default Syntax
None
This command does not have a default key assignment. You can either
assign a key to the command using the Assign Key command or issue the
command using Execute Editor Command.
Description
This command encrypts one or more lines of a file. The purpose of
encryption is to render a file or selected portions of a file unreadable,
while preserving the integrity of the file contents. This function
enables you to secure text by preventing other users from reading a
portion of a file or an entire file.
This command functions similarly to the Encrypt command, except you can
specify a password key when executing this command instead of setting the
encryption key separately using the Set Encryption Key command. If you
use the Encrypt With Key command, you must supply the correct key in
order to decrypt the encrypted text.
This command is especially useful for encrypting only one portion of the
text or the entire file. If you want to encrypt several blocks of text,
it is preferable to first set the encryption key using the Set Encryption
Key command, then use the Encrypt command to selectively encrypt blocks
of text.
