Spring encryption Tool Security3.1 enhanced simplified version

The enhanced version increases the encryption string to 80 bits, and yes, the resulting hash values are not the same.

Output

Password Rapido Match success: Df10352d9f07d49679bd71fc2e7122052572471ffe35f295218f1c41c51aa03eb8071ef339f7a536a190a5bf4f2b34e7b29344108bab B287caf2ddb0e4cb54ade855944707cba3616ead361e3a80b6a74f6ebd5625ba325e8670ed43a14c2f431b3de542912859126701dbfa0deaab9cea8b1 9e285e613fa9a32c7ec25086b99cc018e6a1b9cb937d952019b73d43097c68b6ab9f0eee30351a0a53548b9d758
