What is an OPENPGP_SIGNATURE file?

OPENPGP_SIGNATURE files mostly belong to GnuPG / Kleopatra. A *.OPENPGP_SIGNATURE file stores a detached PGP digital signature, created by cryptography software such as GnuPG (GNU Privacy Guard) or Kleopatra. It contains a cryptographic signature that can be used to verify the authenticity and integrity of a separate data file. The signature file is created by generating a cryptographic hash of the data file and then encrypting that hash with the signer's private key. A recipient can then use the signer's public key, contained within a *.ASC file or similar, to decrypt the signature and compare it to a newly generated hash of the data file. A match confirms that the file has not been tampered with and originated from the expected sender. Detached signatures are commonly used for emails and software downloads.
