ocsp attribute

Type:boolean
Inherited:no
Used By:input
See:algorithm alias handler keypassword keystoretype location pades password reason signer timestampurl

Causes the signature to run an ocsp and CRL verification against the Certificates at the time of signing. This step involves network traffic to several remote servers, and when used with the timestampurl attribute the result is a signature that has "long-term validation". This is only used by the input type="signature" element, and is not mandatory.

This shows how to digitally sign a document

<input type="signature"
       handler="acrobat6"               // handler used to verify this signature
       keystore="file:/privatekey.jks"  // URL of the keystore
       keystoretype="JKS-SUN"           // type of keystore
       password="storepassword"         // password to unlock the keystore
       alias="secretkey"                // key from the keystore to use
       keypassword="secretkeypassword"  // password to unlock the key, if required
       signer="John Smith"              // name to place on the signature
       reason="I am the author"         // reason you're signing the document
/>

Same as the above example but showing the additional keys that might be used to create a signature with "long-term validation".

<input type="signature"
       handler="acrobat6"               // handler used to verify this signature
       keystore="file:/privatekey.jks"  // URL of the keystore
       keystoretype="JKS-SUN"           // type of keystore
       password="storepassword"         // password to unlock the keystore
       alias="secretkey"                // key from the keystore to use
       keypassword="secretkeypassword"  // password to unlock the key, if required
       signer="John Smith"              // name to place on the signature
       reason="I am the author"         // reason you're signing the document
       timestampurl="http://timestamp.entrust.net/TSS/RFC3161sha1TS" // URL of the RFC3161 Timestamp service
       pades="true"                     // Mark the signature as PAdES compatible
       ocsp="true"                      // Perform OCSP and CRL verification at time of signing
       algorithm="SHA256"               // Set the digest algorithm to SHA-256 (optional).
