How to find out the encryption algorithm by the public key and signature example?

Question

Cryptography

At work, a certain butt is used, which signs texts using a public key. The program is over 10 years old, no sources, no docks, no developers.
There was a need for another program to verify these signatures. Accordingly, the question is - can I somehow find out the applied algorithm (I want to believe, not self-written), if I have a public key and an example of a signature in my hands?
key:

0602000000000000525341310002000001000100C3506F92C9B415D2B4A85C16F2CA3D38331

48F3DD25F9211327BC

signature:

8BEFE4A664F37179446530A6F6D1723F2C526C69D65F14AF64BCC681B5CE2A5F383C615BDB

(in fact, there are no hyphens in the key or in the signature, I inserted hyphens, otherwise a part is cut off on the page)

Answer 1

The given public key is an encoded key blob in WinAPI format. RSA algorithm, key length 512 bits (not enough).
PS. He wrote garbage about the hash, first hash encryption, then encryption. So you need to decrypt the signature with the public key and see what happens there.
