To verify a certificate, the recipient first extracts the plaintext information and hashes it using the same hash function used by the CA. Simultaneously, the recipient decrypts the digital signature using the CA's public key to recover the original hash code.
Conditions: The recipient has the signed certificate.; The recipient possesses the correct public key of the issuing CA.; The recipient uses the same cryptographic hash function as the CA.
