Getting information on certificates
Y

Y
ou cannot change information in the dialog box, but you can copy text from it.
To get information on a certificate
:
1
L
og in to your profile, and choose Tools > Self-Sign Security > User Settings.
2 Do one of the following
:
•
To get information on your own certificate, select User
I
nformation in the left pane of
the User Settings dialog box. Under Certificate, click Details. When other users import
your certificate, they’ll probably ask you to check your fingerprint information against
the information they receive with the certificate.
•
To get information on a certificate in your list of trusted certificates, select Trusted
Certificates in the left pane of the User Settings dialog box, select the certificate in the
list, and click Details.
3
I
n the Certificate Attributes dialog box, note the following
:
•
The serial number is a unique number that ensures no two certificates from the same
DN can be identical.
•
The validation period specifies a span of time in which the certificate is valid.
I
t begins
with the date and time the certificate was created.
•
The distinguished name (DN) is the name, organization, and country that the user
provided when they created the profile.
I
n Acrobat Self-Sign Security, the user DN and
the certificate issuer DN are the same because a certificate is always issued by the user,
rather than by a third-party authority.
•
The fingerprint information can be used to compare the signature information with the
user certificate information to make sure the certificate came from the user it repre-
sents.
4 Click Close to exit the dialog boxes.
Changing
user
settings
in
Self-Sign
Security
Y
ou can change password options and create or edit signature appearances for Self-Sign

prompts for a password. Changing your password does not change your signature.
By default, your profile is preset to prompt for a password every time you sign a
document.
Y
ou can change it to prompt only after a certain period of time has elapsed or
to never prompt for a password.

Creating a new signature appearance
Y

that it can meet legal requirements.
To create a new signature appearance
:
1
I
f you want to include a graphic (such as a scanned signature or logo) in your signature,
create or import a picture from any authoring application, place the graphic on a page by
itself, and convert the file to PDF.
When you use the picture in a signature, Acrobat Self-Sign Security copies only the picture
out of the page, not the white space around it. Self-Sign Security crops and scales the
picture to fit in the signature field.
