Overview of Digital Signature — Cheap Digital Signature Service
Pursuant to Clause 6, Article 3 of Decree 130/2018/ND-CP detailing the implementation of the Law on Electronic Transactions with regard to digital signatures and authentication services:
"A digital signature is a form of electronic signature created by transforming a data message using an asymmetric cryptographic algorithm. This process lets the recipient identify:
a) The transformation was performed with the private key matching the corresponding public key;
b) The integrity of the message’s content remained intact after transformation."
Simply put, a digital signature is a tool that contains the identification information of an Enterprise or an individual and serves as a substitute for a handwritten signature on electronic documents. It plays a crucial role in online transactions, from filing taxes, submitting social insurance, declaring customs, to issuing electronic invoices.
Using a cheap digital signature service helps businesses remain compliant with regulations while delivering numerous practical benefits:
- Security and safety: Each digital signature is uniquely encrypted and cannot be forged.
- Legal validity: It is recognized as having the same legal weight as a handwritten signature in electronic documents.
- Convenience and cost-efficiency: Sign documents remotely without needing to print or submit physical copies.
