SetSignProcessSignaturePolicy

Security and Signatures

Description

Sets the CAdES signature-policy-identifier signed attribute for the PAdES-B-B signing path.

Syntax

Delphi

Function SetSignProcessSignaturePolicy(SignProcessID: Integer; Const PolicyOID, PolicyHashHex: WideString; HashAlgorithm: Integer): Integer;

Parameters

SignProcessID	Value returned by one of the NewSignProcessFrom* functions.
PolicyOID	Dotted-decimal OID identifying the policy document. Pass an empty value to clear the attribute.
PolicyHashHex	Hex-encoded hash of the policy document.
HashAlgorithm	Digest code: 0 auto/SHA-256, 1 SHA-1, 2 SHA-256, 3 SHA-384, 4 SHA-512.

Returns

Returns 1 when the process exists and the hash-algorithm code is accepted; returns 0 otherwise.

Remarks

Odd-length or non-hex policy hash input is truncated at the first invalid pair. The attribute is emitted only for the ETSI.CAdES.detached SubFilter path.
