How to use PDF Signer 9.0 to sign PDF documents
To use PDF Signer 9.0 to sign PDF documents, you need to have a digital certificate that identifies you as the signer. A digital certificate is a file that contains your name, email address, public key, and other information, as well as a digital signature from a trusted authority that verifies your identity. You can obtain a digital certificate from a certificate authority (CA), such as VeriSign, Comodo, or DigiCert, or you can create your own self-signed certificate using PDF Signer 9.0.
Once you have a digital certificate, you can use PDF Signer 9.0 to sign PDF documents using different methods, depending on where your certificate is stored and how you want to sign your documents. Here are some of the most common methods:
How to create and manage digital certificates
If you don't have a digital certificate from a CA, or if you want to create your own self-signed certificate for testing purposes, you can use PDF Signer 9.0 to create and manage digital certificates. To do so, follow these steps:
Open PDF Signer 9.0 and click on the "Certificates" tab
Click on the "Create Certificate" button
Fill in the required fields, such as your name, email address, organization name, country code, etc.
Choose the key length (2048 bits or higher recommended) and the validity period (up to 10 years)
Click on the "Create" button
Choose a password to protect your private key and click on the "OK" button
Choose a location and a file name to save your certificate and click on the "Save" button
You have successfully created a self-signed certificate using PDF Signer 9.0. You can now use it to sign PDF documents. However, keep in mind that self-signed certificates are not trusted by default by other parties, so they might not accept your signature as valid. To make your signature more trustworthy, you need to obtain a certificate from a CA or have your self-signed certificate signed by a CA.
To manage your existing certificates, you can use the "Certificates" tab in PDF Signer 9.0. Here you can view, edit, delete, export, or import certificates from different sources.
How to sign PDF documents using certificates from the Microsoft Certificate Store
If you have a certificate from a CA or a self-signed certificate that is stored in the Microsoft Certificate Store on your computer, you can use PDF Signer 9.0 to sign PDF documents using this method:

How to configure the signature appearance and position
PDF Signer 9.0 allows you to customize the appearance and position of your signature on the PDF document. You can choose from different options, such as:
The page number and the location (top, bottom, left, right, center) where you want to place your signature
The size (width and height) of your signature in pixels or percentage
The text that you want to display next to your signature, such as your name, title, date, reason, etc.
The font, color, and alignment of your text
The image that you want to use as your signature, such as a scanned signature or a logo

How to add timestamps and encryption to your signatures
PDF Signer 9.0 also allows you to add timestamps and encryption to your signatures for extra security and validity. A timestamp is a date and time that is added to your signature by a trusted time stamping authority (TSA). It proves that your document was signed at a specific point in time and prevents backdating or tampering. Encryption is a process that scrambles your document data and makes it unreadable without a password. It protects your document from unauthorized access or modification.
To add timestamps and encryption to your signatures, you can use the "Advanced" tab in PDF Signer 9.0. Here you can:
Select a TSA server from the list or enter a custom URL
Enter the username and password for the TSA server if required
Select the hash algorithm for the timestamp (SHA 256/512 recommended)
Select the encryption algorithm for the document (AES 128/256 recommended)
Enter the password for opening and modifying the document
Select the permissions for printing, copying, or modifying the document
After configuring these settings, you can sign your document as usual and it will be automatically timestamped and encrypted.
How to verify and validate PDF signatures
After signing a PDF document with PDF Signer 9.0, you might want to verify and validate its signature. Verifying a signature means checking its status and properties, such as who signed it, when it was signed, what certificate was used, etc. Validating a signature means checking its authenticity and integrity, such as whether it was issued by a trusted CA, whether it has been revoked or expired, whether it has been modified after signing, etc.
You can verify and validate PDF signatures using different methods, depending on what software or standard you want to use. Here are some of the most common methods:

A valid digital signature must meet the following requirements:
It must be created by a person who has the intent and authority to sign the document
It must be based on a valid digital certificate that is issued by a trusted CA or self-signed by the signer
It must use a secure and robust algorithm and key length, such as SHA 256/512 and RSA 2048 or higher
It must include a timestamp that proves when the document was signed
It must not be altered or tampered with after signing
It must be verified and validated by the recipient using the appropriate software or standard
