The Crypto commands enable you to encrypt and decrypt strings and files. SWF Studio uses 448-bit blowfish encryption/decryption.
To encrypt a file you provide a path to the source and destination files, and a key that will be used to encrypt the file. Then when you want to decrypt the file you provide the path to the source and destination files, and the same key used to encrypt the file. The same situation is true for a string, only you provide the data as a string and an encrypted, or decrypted, string is returned.
