Verify Digital Signatures ​

Verifying a digital signature consists of signature validity and certificate trustworthiness.

• Signature validity indicates that the document has not been tampered with.
• Certificate trustworthiness confirms that the signer is trustworthy.

Generally, a signature is verified only when both the signature is valid and the certificate is trustworthy.
