How to find out how a string is encrypted, knowing what is encrypted in it?

Question

Cryptography

Good afternoon friends.
The essence of the question is this:
I have this line C57138179B2553DD.
I know that Epower is encrypted there.
Help me identify an encryption tool, I need to decrypt a few more lines.
You are welcome.
Or indicate in which direction to dig.

Answer 1

I am not a very security specialist, but a certain key is usually used for encryption, it is also a salt, because the same algorithm with a different key will give a different result. Without it, it will be quite difficult to decipher, I think.

Answer 2

Unless you try all known checksum algorithms.

Answer 3

Try typing "Epower" here:

If there is no such option, then it is most quickly encrypted with a salt.
You can try to find out the hash type here:

Possible algorithms for your hash:
- MySQL, MySQL323
- Oracle 7-10g, DES(Oracle)
- CRC-64
- SAPB
- substr(md5 ($pass),0,16)
- substr(md5($pass),16,16)
- substr(md5($pass),8,16)
