Click on Cancel on the toolbar to recall the recently submitted document for signing.

Enter the reason, then click Agree to complete the document recall. The system will send a notification email to the submitter and the approvers.

History

Displays the actions during the creation of a document for signing, including:

• The time and person who created the document.
• The time and person who completed the setup.
• Email sending details to users, including the sending time.
• The time and person who signed the document.
• Information on downloading related documents.
• Information on delegation, rejection, and cancelation with reasons.

Download document

Click on Download to download files and history of signing document:

• Download Original Proposal: Users can download the document or file they previously uploaded to the signing system.
• Download Signed Proposal: The system allows users to download the document file with all signatures from the participating parties. Note: The signed proposal can only be downloaded when its status is "Approved."
• Download Proposal History: Allows users to download a file that displays the complete action history performed by users during the online signing process. The content is displayed as shown below:

Signature Verification

For the "Completed" status: Users can verify the validity of the signature by:

• Clicking on the “...” icon
• Selecting “Validate” to proceed with signature verification.

The verification information will be displayed as below:

1. Signer Information: This section provides basic identification details of the individual who signed the document, including:

• Signer’s Name: The displayed name extracted from the digital certificate used for signing.
• Signing Time: The exact timestamp when the document was digitally signed.
• Signature Status: Valid / Invalid, with reasons provided if invalid (e.g., expired certificate, revoked certificate, document modified after signing, etc.).

2. Valid Signature Details: This section verifies the integrity and trustworthiness of the signature. Information includes:

• Last Check: The most recent time the system validated the signature’s status.

• Server Timestamp: The timestamp recorded by the certification authority’s server at the time of signing. This ensures the signature was created while the certificate was still valid.

• Signature Validity:

  • Valid From: The start date and time of the digital certificate’s validity.
  • Valid Until: The expiry date and time of the certificate.

• OCSP/CRL Check Status: Determines whether the certificate has been revoked (if applicable).

3. Cryptography Information: This section relates to the algorithms and technical standards used during the signing and verification process, including:

• Signature Algorithm:
  • RSA (Rivest–Shamir–Adleman): A widely used public-key cryptosystem for creating and verifying digital signatures.
• Hash Algorithm:
  • SHA-512 (Secure Hash Algorithm 512-bit): Generates a fixed hash value from the document’s content to detect any post-signing alterations.
• Signature Format Standard:
  • CADES (CMS Advanced Electronic Signatures): An advanced digital signature standard based on CMS (Cryptographic Message Syntax). CADES ensures that:
    • The document remains unchanged after signing.
    • Additional information such as signing time, digital certificates, certificate chains, etc., can be embedded.
    • Various security levels are supported: CAdES-B, CAdES-T, CAdES-LT, etc., where:
      • CAdES-T includes a timestamp.
      • CAdES-LT adds long-term validation information.
