Operation Example

Encrypt is an operation that will encode your image so that it cannot be visually identified. Only when the encrypt operator is used on the image with the same password again, will it become intelligible. There are 2 strong warnings to keep in mind when using this operator:

Warning: 1) It's essential that you save encrypted images in lossless formats. If you save your image as a jpeg, for example, jpeg compression alters the data slightly to make it more compressable, this will make the image so that it can never be fully restored. This example was taken from the top example, saved in a lossy format and decrypted Some common lossless formats include: 32 or 24 bit versions of TIFF, TARGA, TRIM, PNG, and 24 bit BMP. 2) It's important to note that encrypting and decrypting are the same operation, so that if an improper password is entered, the encrypted image is further encrypted with the new password. Thus it is nessecary to decrypt the image with both the incorrect password and the proper password. On the other hand, this allows for virtually unlimited encryption levels. The order in which the passwords are entered to decrypt is not important, just that the passwords are correct every step of the way

Password

The password must be between 8 and 50 characters, and is case-sensitive.

This parameter functions within the timeline, it will accept different strings at any level. For example, the timeline will accept a filename or password at any frame, and that will become the current setting at any particular time.
