Public Methods
public static byte[] calculateDigest (DigestAlgorithm in_digest_algorithm_type, byte[] in_message_buf)
Calculates a digest of arbitrary data. Useful during CMS generation custom signing workflows for digesting signedAttributes before sending off for CMS signatureValue generation (e.g. by HSM device or cloud signing platform).
Parameters
| in_digest_algorithm_type | -- the digest algorithm to use |
|---|---|
| in_message_buf | -- the message to digest |
Returns
- a container of bytes corresponding to the digest of the message
Throws
| PDFNetException |
|---|
public static byte[] signDigest (byte[] digest_buf, DigestAlgorithm digest_algorithm_type, byte[] pkcs12_buf, String pkcs12_password)
Sign the digest of arbitrary data with private key in the provided PKCS #12 key file (.pfx). This function is part of the low-level custom signing API, and works with GenerateESSSigningCertPAdESAttribute, GenerateCMSSignedAttributes, and GenerateCMSSignature.
Parameters
| digest_buf | -- The digest to sign |
|---|---|
| digest_algorithm_type | -- The digest algorithm used to generate the digest |
| pkcs12_buf | -- The buffer containing the PKCS #12 key (as usually stored in .pfx files) to use for signing |
| pkcs12_password | -- The password to use to parse the PKCS 12 key |
Returns
- the DER-serialized bytes of the signature
Throws
| PDFNetException |
|---|
public static byte[] signDigest (byte[] digest_buf, DigestAlgorithm digest_algorithm_type, String pkcs12_keyfile_path, String pkcs12_password)
Sign the digest of arbitrary data with private key in the provided PKCS #12 key file (.pfx). This function is part of the low-level custom signing API, and works with GenerateESSSigningCertPAdESAttribute, GenerateCMSSignedAttributes, and GenerateCMSSignature.
Parameters
| digest_buf | -- The digest to sign |
|---|---|
| digest_algorithm_type | -- The digest algorithm used to generate the digest |
| pkcs12_keyfile_path | -- The path to the PKCS #12 keyfile (usually has a .pfx extension) to use for signing |
| pkcs12_password | -- The password to use to parse the PKCS #12 keyfile |
Returns
- the DER-serialized bytes of the signature
Throws
| PDFNetException |
