What is Digital Signature?

A digital signature is a cryptographic technique that verifies the authenticity and integrity of digital messages or documents. It serves as a digital equivalent of a handwritten signature or a stamped seal with additional security features.

How digital signature works?

1. Key Generation

The process begins with the generation of a pair of cryptographic keys – a private key and a public key. The private key is kept secret and known only to the signer, while the public key is shared with others.

2. Signing the Document

To sign a document or message, the sender uses their private key to create a unique digital signature. This signature is a mathematical representation of the document’s content and is appended to the document.

3. Verification

To verify the signature, the recipient uses the sender’s public key to decrypt the signature and compare it with a newly calculated digital signature based on the received document. If the two signatures match, the document is considered authentic and unaltered.

Features of Digital Signature

Universal Signing Platform

An all-round universal platform that supports multiple eKYC and CA providers – allowing you to make your preferred selection without vendor lock-in – with more providers to be added in the future.

Highly Secure & Protected

Documents and digital signatures are always protected thanks to maximum security measures such multi-layered encryption and firewalls, strong 2FA, KMS, anti-DDOS and Ransomware, a 24/7 SOC and much more.


SigningCloud automatically ‘locks’ a document after it’s signed and finalised, preventing anyone from making unauthorised modifications to it without being detected by any common PDF document viewing tool.

Long-Term Validation

E-signatures are embedded with top-notch PKI technology to ensure long term validation and non-repudiation, adhering to European Telecommunications Standards Institute (ETSI) 102 778-1 PDF Advanced Electronic Signatures (PAdES) standard.


Any e-signature is valid and enforceable under the Electronic Commerce Act 2006 and Digital Signature Act 1997 if the signature is verifiable by a valid digital certificate issued by a licensed CA in Malaysia.

Transparent & Seamless

Traceable, trackable and fool proof – sign anytime, anywhere with almost any device with a secure audit trail.
