Oracle hmac_md5 encryption method with Key, call Java implementation
Recently, there is a need for a peripheral system interface. The other party requires the message to be encrypted by hmac_md5 with Key. After searching on the Internet, I found that Oracle provides a standard API, as follows. FUNCTION MD5(PASSWD IN VARCHAR2) RETURN VARCHAR2 IS –PASSWD characters to be encrypted –@REMARK: MD5 encryption retval varchar2(32); […]
Network security – Base64 encoding, MD5, SHA1-SHA512, HMAC (SHA1-SHA512) hashing
1. Base64 encoding Base64 encoding requires converting three 8-bit bytes (3*8=24) into four 6-bit bytes (4*6=24), and then in Two 0s are added in front of the 6 bits to form a byte of 8 bits, so that the effective bits of each byte are 6 bits, and the value range is 0~630 ~ (2^6 […]
JAVA is encrypted with HmacSHA1 and the returned array is encrypted with Base64
1. The following methods can be used for encryption through HmacSHA1 public static byte[] HmacSHA1Encrypt(String encryptText, String encryptKey) throws Exception { byte[] data = encryptKey. getBytes(“UTF-8”); // Construct a key according to the given byte array, the second parameter specifies the name of a key algorithm SecretKey secretKey = new SecretKeySpec(data, “HmacSHA1”); // Create a […]
