In the world of digital solutions, security is key. And one of the most important mechanisms that guarantees this security is precisely the cryptographic envelope. Although it sounds like a term from a spy movie, it's actually an everyday component of electronic signatures that protects your data, identity and proof of document signing.
A cryptographic envelope is a A digital package that bundles the document, the electronic signature and all the information needed to verify it.
It is because of her:
It's like putting a traditional paper document in an envelope, sealing it and stamping it with your name and the date.
Don't. Although the CAdES signature (with an extension of .p7s), it every qualified electronic signature - including XAdES and PAdES - uses a cryptographic envelope, albeit in its own way.
Format | Envelope type | Can it be called a cryptographic envelope? | Example |
CAdES | Yes - always | Yes, the file .p7s or .asice is a classic envelope | contract.docx.p7s |
XAdES | Yes - often | Yes, especially when a container is used .asice | invoice.xml.asice |
PAdES | Yes - but "embedded" | Yes, although the signature is embedded in the PDF, the PDF file becomes both a document and an envelope | offer.pdf |
As you can see, each of these formats creates its own version of the cryptographic envelope - sometimes as a separate file, sometimes as a container, and sometimes as an embedded signature.
Note: different technical approaches, same idea
Thanks to the envelope:
When signing a document in proCertum SmartSign, you can choose your preferred format: PAdES, CAdES or XAdES. The application itself creates the appropriate cryptographic envelope:
The application automatically embeds the certificate, timestamp (if you choose) and takes care of the correctness of the structure.
WebNotarius is a web application from Asseco that allows:
It's an ideal tool when you need to confirm the authenticity of a signature, but don't want to install additional programs.
For anyone who:
archives documents for many years and wants to ensure their long-term validity.
In summary, kcrypto operta is not an add-on - it is the foundation of a secure electronic signature. It is what makes the signed document:
Solutions from Asseco -. proCertum SmartSign i WebNotarius - create and handle envelopes automatically. You just sign, and all the cryptography happens in the background.
