@theglauber Yes, you can use the module without Spring Security or the Spring framework. You can also perform streaming encryption if you'd like.     /** number of rounds used given AES key set on this instance. *  It's code was originally derived from the illustrative Rijndael Java     if (traceLevel > 0)    traceInfo += " = "+Util.toHEX1(a)+"n"; How can I create my own key?         if (traceLevel > 2)    traceInfo += "nt AK = "+Util.toHEX1(ta); */

    testAES.setKey(key);        // set key and display trace info

Salts are necessary for PBKDF2, which is why the API for password-based encryption requires them as input for key derivation. Advanced Encryption Standard is built from three block ciphers: AES-128, AES-192, and AES-256. @erickson: that is exatly what i need to do (derive an AES key from a password). Here is a class to encrypt/decrypt data using 256 bits AES encryption algorithm (aka Rijndael).             // InvMixColumns(state) into a         int i, j;      * See pseudo code in Fig 5, and details in this section.     58, -111, 17, 65, 79, 103, -36, -22, -105, -14, -49, -50, -16, -76, -26, 115, 128-bit keys have 10 rounds, 192-bit keys have 12, and finally 14 rounds for 256-bit keys.             sb.append((char) n);         byte[] w0 = new byte[ROUND_KEY_COUNT];

Why do i have more particles in the render than the viewport?         }         row = i % COL_SIZE; The key size can be reduced to 128 bits, which is still considered "strong" encryption, but it doesn't give much of a safety margin if attacks are discovered that weaken AES.     /** AES encryption S-box. rev 2020.10.26.37891, Stack Overflow works best with JavaScript enabled, Where developers & technologists share private knowledge with coworkers, Programming & related technical career opportunities, Recruit tech talent & build your employer brand, Reach developers & technologists worldwide. */ Here,when defining the secret key, we prevented the algorithm from being taken as a parameter with getInstance method and initialized the KeyGenerator by setting keysize 256.     -4, 86, 62, 75, -58, -46, 121, 32, -102, -37, -64, -2, 120, -51, 90, -12,
