Our cryptographic system will use the following scheme: Encryption AES using CBC mode with a 256 key; Key generated by PBKDF2 hashing with HMAC-SHA512, using 100k interactions and a random salt of 16 bytes; IV randomly generated Created on Plnkr: Helping developers build the web.

The AES algorithm is an iterative, symmetric-key block cipher that supports cryptographic keys (secret keys) of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits.The below figure shows the high-level AES algorithm: If the data to be encrypted doesn't meet the block size requirement of 128 bits, it must be padded. We encrypt our data with a symmetric encryption method, that uses the same key for encryption and decryption. In our case we are going to use the AES-encryption method. We encrypt our key (for ... AES Algorithm. The Advanced Encryption Standard (AES) is a symmetric encryption algorithm. The algorithm was developed by the two Belgian cryptographers Joan Daemen and Vincent Rijmen. AES was designed to be efficient in both hardware and software and supports a block length of 128 bits and key lengths of 128, 192 and 256 bits.

Advanced Encryption Standard (AES) is a famous and robust encryption method for encrypting the data (string, files). Crypto-js is a JavaScript library provided to achieve AES in JavaScript without the help of any other language like Java, C#. Here, we are going to learn how to encrypt and decrypt the data strings using crypto-js. The above is the java encryption process, but the key bit 20. If I change the key to 16 bits, the following can be correctly decrypted; but if it is 20 bits, it cannot be decrypted properly. To use AES encryption in C# we need to add a class file named "ClsCrypto.cs". Here is the code for ClsCrypto class : In ClsCrypto method we have a parameter for "strPassword", it will be same when we decrypt using javascript code. We need to include aes.js and pbkdf2.js javascript files to use this code. These files can be downloaded ...
