SSL Certificate
Deploy an SSL certificate to enable HTTPS encryption of websites, trusted identity authentication and prevent against data leaks or tampering during transmission.
Get SSL Certificate →All document signing certificates Root certificate have been entered into the root Adobe and Microsoft root certificate library trust lists, which means that document signatures are fully recognized and trusted, and support global use.
When a digitally signed document is modified, an "X" will be printed at the signature area to remind the user that the document has been modified after signing, ensuring the integrity, authenticity, and legality of the document.
Support all mobile platforms, Adobe series products and Office series products for document signature formats.
The private key of the document signing certificate is stored in a UKey or encryption machine, providing a high level of security protection for the certificate while also possessing the characteristics of convenience and time saving.
The document signature certificate meets the legal and regulatory requirements for electronic document signing in multiple countries and industries, including the Electronic Signature Law, HIPAA, FDA, eIDAS, ESIGN and UETA in the United States.
By using a timestamp, even if the certificate originally used for signing has expired, the signed document signature will never expire.


Financial institutions have a large number of paper documents (such as investment contracts, insurance agreements, bank statements) that can be signed using document signature certificates to ensure that electronic document signatures comply with relevant laws and regulatory review requirements, ensuring their authenticity, validity, legality, and compliance.

Document Signing Certificate is designed to apply in paperless office operations to digitally sign any document.
Document signing certificate can authenticate sender's identity and the recipient also can review a trusted digital signature on the document.
Compliant with industry standards, Document Signing Certificate support RSA algorithm, 2048+bit keys, SHA256-bit encryption to protect critical business documents.
Documents signed with the trusted Document Signing certificates comply with the U.S. Federal ESIGN Act, European Union's eIDAS and other international laws.
Digital signatures created by Document Signing Certificates can be timestamped and include an audit trail that never expires.
Sectigo Document Signing certificate offer unlimited signatures in its lifetime.
A Document Signing Certificate is an electronic file issued by a Certificate Authority (CA). It contains a pair of secure digital key for assuring signer's identity authentication and integrity of electronically transmitted documents.
Digital signatures, like handwritten signatures, are unique to each signer. It uses public key infrastructure (PKI), which is considered the gold standard for digital identity authentication and encryption. PKI relies on the use of two related keys, a public key and a private key, that together create a key pair to encrypt and decrypt a message using strong public key cryptography algorithms.
Validation is an important part of certificate issuing process. Take Sectigo for example, and this is the validation materials needed below:
The validation work is done by Sectigo. You are required to respond to emails, follow instructions and provide the requested documents.
