As mentioned above ----->>> Signatures x509 certificates - Tokens - time stamp - hash file - private keys
- Signatures x509 certificates: Bitcoin does not use X509 certificates. Read this: What are the DER signature and SEC format
- Tokens: What kinds of tokens? Probably not related to Bitcoin.
- Time stamp: timestamps are just timestamps. What do you want to do with them?
- Hash file: I don't know what that is or how it might relate to Bitcoin.
- Private keys: Private keys in Bitcoin are typically encoded using the WIF format, which is base 58 and not hex. If you have private keys and they are not WIF, then they are probably not related to Bitcoin.
They are uses for mining i think ------>>> I don't know why they gave me the key infrastructure x509 crts
