Of course, for Java EE developers, the topic of security may be less familiar, and user authentication and authorizatio

In Java with aes256 encryption, but found that Java can not use pkcs7padding, and Java is the pkcs5padding fill, the solution is, Use the Bouncycastle component to enable pkcs7padding padding inside java.Saying spicy is more than the code:public class Aesutil {/*** Encodes a String in AES-256 with a given key** @param context* @param password* @param text* @retur

Advanced Encryption Standard (English: Advanced encryption Standard, abbreviation: AES), also known as the Rijndael encryption method in cryptography, is a block encryption standard used by the U.S. federal government. This standard, which replaces the original DES, has been analyzed and widely used worldwide. After five years of selection process, the Advanced Encryption Standard was issued by the National Institute of Standards and Technology (NIST) on November 26, 2001 in FIPS PUB 197 and bec
