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:
- 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.).
- 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OCSP/CRL Check Status: Determines whether the certificate has been revoked (if applicable).
- 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.
- CADES (CMS Advanced Electronic Signatures): An advanced digital signature standard based on CMS (Cryptographic Message Syntax). CADES ensures that:
