The problem is there are a lot of pitfalls regarding cryptography and it is extremely easy to build a system that looks secure for the layman but is trivial to break for a knowledgeable attacker. AES stands for Advanced Encryption Standard. We'll start by looking at the AES, or Advanced Encryption Standard, as that is the standard, we will be used to encrypt and decrypt the information.. For encryption, you can either enter the plain text, password, an image file or a .txt file that you want to encrypt. Now choose the block cipher mode of encryption. ECB(Electronic Code Book) is the simplest encryption mode and does not require IV for encryption. The input plain text will be divided into blocks and each block will be encrypted with the key provided and hence identical plain text blocks are encrypted into identical cipher text blocks. CBC mode is highly recommended and it requires IV to make each message unique. If no IV is entered then default will be used here for CBC mode and that defaults to a zero based byte[16].

Also, imagine now that we use AES in ECB mode to encrypt the data in the database, but we now use the same key to encrypt every single entry. If an attacker breaks into our database and steals our data.. I should say that although GCM has both encryption and message integrity, it is a very fragile design: if you re-use an IV, you are screwed -- the attacker can recover your key. Other designs are less fragile, so I personally am afraid to recommend GCM based upon the amount of poor encryption code that I have seen in practice.XTS: An IV-based encryption scheme, the mode works by applying a tweakable blockcipher (secure as a strong-PRP) to each n-bit chunk. For messages with lengths not divisible by n, the last two blocks are treated specially. The only allowed use of the mode is for encrypting data on a block-structured storage device. The narrow width of the underlying PRP and the poor treatment of fractional final blocks are problems. More efficient but less desirable than a (wide-block) PRP-secure blockcipher would be.If for some reason you cannot use a high level crypto library, for example because you need to interact with existing system in a specific way, there is no way around educating yourself thoroughly. I recommend reading Cryptography Engineering by Ferguson, Kohno and Schneier. Please don't fool yourself into believing you can build a secure system without the necessary background. Cryptography is extremely subtle and it's nigh impossible to test the security of a system.

Also, it is important to understand the difference between message integrity and encryption. Encryption hides data, but an attacker might be able to modify the encrypted data, and the results can potentially be accepted by your software if you do not check message integrity. While the developer will say "but the modified data will come back as garbage after decryption", a good security engineer will find the probability that the garbage causes adverse behaviour in the software, and then he will turn that analysis into a real attack. I have seen many cases where encryption was used but message integrity was really needed more than the encryption. Understand what you need. AES - Advanced Encryption Standard - is the successor to DES. AES-GCM (AES operating in Galois/Counter Mode (GCM)) is preferred (check this blog post too) But if the intended output is an image or .txt file then you can use this tool to convert the base64 encoded output to an image.

Note that most of these require the IV to be random, which means non-predictable and therefore should be generated with cryptographic security. However, some require only a "nonce", which does not demand that property but instead only requires that it is not re-used. Therefore designs that rely on a nonce are less error prone than designs that do not (and believe me, I have seen many cases where CBC is not implemented with proper IV selection). So you will see that I have added bold when Rogaway says something like "confidentiality is not achieved when the IV is a nonce", it means that if you choose your IV cryptographically secure (unpredictable), then no problem. But if you do not, then you are losing the good security properties. Never re-use an IV for any of these modes. AES One. The Safest Project.

The parallelizability of the mode often makes it faster, in some settings much faster, than other confidentiality modes. An important building block for authenticated-encryption schemes. Overall, usually the best and most modern way to achieve privacy-only encryption.CBC, OFB and CFB are similar, however OFB/CFB is better because you only need encryption and not decryption, which can save code space.

IF the code required to implement CBC is much smaller than that required for CTR (I don't know this is true, it's just an example), then I could understand why the mode with the smaller code would be preferred. But if I am writing an app that runs on a server, and the AES library I am using implements both CBC and CTR anyway, then this criterion is irrelevant. 192 bit AES-COUNTER. k GCM: A nonce-based AEAD scheme that combines CTR mode encryption and a GF(2128)-based universal hash function.

AES provides 128 bit, 192 bit and 256 bit of secret key size for encryption. Things to remember here is if you are selecting 128 bits for encryption, then the secret key must be of 16 bits long and 24 and 32 bits for 192 and 256 bits of key size. Now you can enter the secret key accordingly. By default, the encrypted text will be base64 encoded but you have options to select the output format as HEX too.

To prevent padding oracle attacks and changes to the ciphertext, one can compute a message authentication code (MAC) on the ciphertext and only decrypt it if it has not been tampered with. This is called encrypt-then-mac and should be preferred to any other order. Except for very few use cases authenticity is as important as confidentiality (the latter of which is the aim of encryption). Authenticated encryption schemes (with associated data (AEAD)) combine the two part process of encryption and authentication into one block cipher mode that also produces an authentication tag in the process. In most cases this results in speed improvement.

CBC: An IV-based encryption scheme, the mode is secure as a probabilistic encryption scheme, achieving indistinguishability from random bits, assuming a random IV. Confidentiality is not achieved if the IV is merely a nonce, nor if it is a nonce enciphered under the same key used by the scheme, as the standard incorrectly suggests to do. Ciphertexts are highly malleable. No chosen ciphertext attack (CCA) security. Confidentiality is forfeit in the presence of a correct-padding oracle for many padding methods.

Ciphertexts are malleable. No CCA-security. Encryption inefficient from being inherently serial. Scheme depends on a parameter s, 1 ≤ s ≤ n, typically s = 1 or s = 8. Inefficient for needing one blockcipher call to process only s bits . The mode achieves an interesting “self-synchronization” property; insertion or deletion of any number of s-bit characters into the ciphertext only temporarily disrupts correct decryption. Advanced Encryption Standard (AES): Published as a FIPS 197 standard in 2001. AES data encryption is a more mathematically efficient and elegant cryptographic algorithm, but its main..
