esignature validations

[Repstien]

How do I  add validation information for e-signature using Adobe Pro X?

Validation is not available with self-certification.

There are many ways to apply an e signature to a PDF.

There are a number of on-line services where you use a secure logon to access the service and then upload the PDF to the service and have the service either distribute or let authorized users access the file. For this type of service the service provides the authentication and records to show the file has not been altered since was made available.

Within Acrobat and Reader there is the user's digital certificate This digital certificate has a private key and a public key. The signer uses his private key to apply his/her digital certificate to the PDF and then in a very secure way, usually a separate email, send the public key to those who need to validate the signature or certificate applied to that PDF. The use needs a pass phrase or password to use the private key. Other users only need to import the public key certificate into their copy of Acrobat or Reader.

You might want to access Adobe's site and learn more about digital certificates and signatures.

Both methods are approved by many countries for digitally signing contracts and other legal documents.

Jurisdictions are looking for a public key validation of the private key used to authenticate.  Adobe refers users to AALT members but only three are listed for Adobe X.

What is AALT. I like the last one listed.

I expect the ones listed were the ones available at the time the help was written. There maybe other sources available now. Look below to see why the list could be out of date. Hint there will be no updates to Acrobat X.

You can send them your copy of your public key certificate. Once the public key certificate is installed the person having your signed document can validate the signature at any time. It is possible their copy of the PDF could be corrupted or modified after you sent them the PDF.

I would also start planning on upgrading your version of Acrobat since Adobe's support to the product ended November 23, 2015.

With a certificate signed document, select the signature field, use the right mouse click to bring up the context menu, select the "validate" option.

On the signature navigation panel there is an option at the top of the panel to validate all.

Symantec has Norton and offer this in their Managed PKI Services,

however they charge $495 per year and your must issue a token ring

device for each, to house the Public key and be a Certificate of

Authority. Makes it cost prohibitive so looking for a CA that can

authenticate and provide the public key.

Do you know if DC Pro generates the Public Key for the private signature?
