Class TimestampHashAlgorithms

Timestamp hashing algorithms

Inheritance

System.Object

TimestampHashAlgorithms

Namespace: IronPdf.Signing

Assembly: IronPdf.dll

Syntax

public sealed class TimestampHashAlgorithms : Enum

The TimestampHashAlgorithms enumeration in IronPDF selects the digest used when requesting a trusted RFC 3161 timestamp during signing.

Part of the IronPdf.Signing namespace, the 3 members are SHA256, SHA512, and SHA1, with SHA256 recommended for most timestamp authorities and SHA1 retained for legacy TSA compatibility. Assign the chosen member to PdfSignature.TimeStampHashAlgorithm alongside the TSA URL.

See Signing PDFs for C# signing code.
