If the PDF is password-protected, include the password:

pplg sign -i input.pdf -o signed.pdf -tk YOUR_API_TOKEN -t YOUR_TENANT_ID -pki CERT_TYPE -pwd PDF_PASSWORD

To specify custom signature position:

pplg sign -i input.pdf -o signed.pdf -tk YOUR_API_TOKEN -t YOUR_TENANT_ID -pki CERT_TYPE -pos '{"page": 0, "left": 200, "bottom": 200, "height": 60, "width": 60}'

To use a custom stamp image:

pplg sign -i input.pdf -o signed.pdf -tk YOUR_API_TOKEN -t YOUR_TENANT_ID -pki CERT_TYPE -pos '{"page": 0, "left": 200, "bottom": 200, "height": 60, "width": 60, "custom_imprint": "/path/to/stamp.png"}'
