Customising electronic signatures

I need to create a signature that has no more than a 3-year expiry.  I also need the signature/certificate that also include a public and private key.

> Is this possible with Adobe Pro?

I have tried to create the signature but it always has a 5-year expiry and it does not seem to have a public key that I can export and send.

Thank you for any help.

PS if it helps the signature/certificate is required for the FDA.

    If you are creating a "Self-Sign" Certificate using Adobe Acrobat, you have no control over the expiration date. If you absolutely need a certificate with a three-year expiration, you'll need to purchase one from a 3rd party vendor. That said, you can export a public key from a Self-Sign Certificate, or any other certificate by selecting Preferences, Signatures, then press the More button under Identities and Trusted Certificates.

     

    However, the FDA may not accept a certificate created by you via Adobe Acrobat DC. I certainly wouldn't. There is no mechanism in Acrobat that verifies that you are, in fact, who you claim to be. Acrobat can only create a Class 1 certificate. You're probably better off getting more details as to the class level of a certificate the FDA will accept and use a vendor that supplies those. Be prepared to be annoyed. The validation process can be cumbersome.

    I was not able to export the public key from the self-sign certificate...perhaps I am misunderstanding the whole concept.

    Once in the "Digital ID and Trusted Certificate Settings" dialog, select a certificate and hit "Export". You can then either email it or save it to a local file.

     


    Hi Joel. I have tried that approach. It does not give me the option to export the public key (or not private key) but directs to give it a file name.

    I ws following instruactions on how to obtain the public key as a file but when i try it does not give me the step to choose.  It may have something to do with not being able to run the programs/settings as an admin.

    Thank you for your efforts.

    Oh well.  Looks like I am going to have to buy a subscription from a Certificate Authority.

    How does you create the signature?
