After consulting colleagues, the company has ready-made MD5 encryption method in crypt library;
Decisively reuse! ! !
Verification: According to the standard md5 algorithm, the string "123456" should be E10ad3949ba59abe 56E057F20F883e.
There are three related to MD5 in crypt library:
Verification 1:- is inconsistent.
Verification 2:- Continuous availability
Call encryption machine SM4 algorithm to encrypt and decrypt data.
Keyboard encoder
-every two bits of data are byte compressed.
-Compress data into bytes.
-decoding: the first 16 bytes obtained.
-decoding: the first 17-32 bytes are converted into bytes.
