Why is the sha1 algorithm a different value? please tell us where it is wrong.

Why is the sha1 algorithm a different value? please tell us where it is wrong. I now have a system developed by someone else. It also uses the sha1 algorithm ..

Now I can calculate a string: 0451bbea51492560499d7af75b424ed096c815e8

System-encrypted: quGLhYR2v0A4Ah3s45EVL6ag134 % 3D

Is it the system's encrypted string, or is it the format converted to another string after sha1 encryption ..
Please kindly advise. How can we make two equal... Which algorithm is used for implementation.

It's hard to see how the code is written.

The length is different, and the natural algorithms are different.

He encrypted it with sha1, and then converted it with the url function?

I can't see his code either. I'm depressed...
He said that he was also calculated by the sha1 algorithm ..

Something is yours, and you cannot see his algorithm. what can I do?

Depends on the code .. I don't know if I don't know ..
