Hello,<br />
I am using openssl to encrypt a largish file(50GB). &nbsp;I have tried using aes128 and aes256, and both take around the same amount of time. &nbsp;I would think that aes256 should take atlease 20% longer than 128, as the program should be doing 4 more iterations. &nbsp;<br />
<br />
I believe aes128 is 10 iterations, and aes256 is supposed to be 14, but based on my observations that may not be happening. &nbsp;<br />
<br />
Is anyone familiar with this tool, or is there a way I'd be able to tell if a file is properly encrypted?<br />
<br />
Thanks for any help provided.

Openssl encryption issues

An algorithm is a self-contained step-by-step set of operations to be performed. Algorithms exist that perform calculation, data processing, and automated reasoning. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.

Algorithms

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.
