Advanced Encryption Standard(AES) is a symmetric encryption algorithm. AES is the industry standard as of now as it allows 128 bit, 192 bit and 256 bit encryption.Symmetric encryption is very fast as compared to asymmetric encryption and are used in systems such as database system. Following is an online tool to generate AES encrypted password and decrypt AES encrypted password. It provides two mode of encryption and decryption ECB and CBC mode. For more info on AES encryption visit this explanation on AES Encryption.

Also, you can find the sample usage screenshot below:

2. This might be a noob question, but I couldn't find its answer anywhere online: why does an OpenSSL generated 256-bit AES key have 64 characters? The command I'm using to generate the key is: $ ope.
3. The way encryption works in AES CTR mode is that we generate some random bits with the encryption key provided and the IV. With these random bits we then XOR them with our string. This creates a randomized text. To decrypt them we just simply XOR the text with the same exact random bits that we generated with the encryption key and the IV.
4. Java AES with CBC using passphrase. Ask Question Asked 6 years, 10 months ago. The key used to encrypt will be different in your OpenSSL command and in your Java program, so the output will be different and incompatible. Java Decryption of openssl aes-256-ctr encrypted file. Key flexibility in java.crypto as in openssl.
5. The AES key is nothing more than a specific sized byte array (256-bit for AES 256 or 32 bytes) that is generated by the keytool (see above).
6. Key generator This page generates a wide range of encryption keys based on a pass phrase. Passphrase: aes-128-cbc: aes-128-cfb: aes-128-cfb1: aes-128-cfb8: aes-128.

Very important note: choice of initial counter is critical to the security of CTR mode. The requirement is that the same counter and AES key combination can never.

Usage Guide

Any plain-text input or output that you enter or we generate is not stored on this site, this tool is provided via an HTTPS URL to ensure that text cannot be stolen.

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].

The AES algorithm has a 128-bit block size, regardless of whether you key length is 256, 192 or 128 bits. When a symmetric cipher mode requires an IV, the length of the IV must be equal to the block size of the cipher. Hence, you must always use an IV of 128 bits (16 bytes) with AES.

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.

Similarly, for image and .txt file the encrypted form will be Base64 encoded.

Below is a screenshot that shows a sample usage of this online AES encryption tool.

AES decryption has also the same process. By default it assumes the entered text be in Base64. The input can be Base64 encoded or Hex encoded image and .txt file too. And the final decrypted output will be Base64 string. If the intended output is a plain-text then, it can be decoded to plain-text in-place.

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.

What is AES CTR

Generate Aes-256-ctr Key West

AES-CTR (counter) mode is another popular symmetric encryption algorithm. It is advantageous because of a few features: 1. The data size does not have to be multiple of 16 bytes. 2. The encryption or decryption for all blocks of the data can happen in parallel, allowing faster implementation. 3. Encryption and decryption use identical implementation.
