pades attribute

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

Causes the signature to be marked as a PAdES signature. signing. 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
       certify="nochanges"              // allow no changes after signing
       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).
