Personal Certificates (S/MIME)
Personal certificates (Personal ID, S/MIME) are used to confirm personal identity and for electronic communication (electronic signature). A message signed with a personal certificate not only proves its origin, authorship, and immutability but also verifies the identity of the sender, as verified and displayed in the personal certificate.

How does electronic signature work?
An electronic signature is a digital method for verifying the identity of the signing person and ensuring the integrity of electronic documents. The fundamental principle is the use of cryptographic technologies that ensure the security, origin, and authenticity of the signed content. Asymmetric cryptography is used in electronic signing, meaning that the person signing the document uses a private key to create the signature. This signature is unique to the document and ensures that any changes in the document after signing will be immediately detected. The recipient uses the signing person's public key to verify the signature, which confirms whether the signature matches the original document. The electronic signature is widely used in electronic communication and enables efficient, quick, and secure document exchange.

Why use electronic signature?
Immutability
A signed e-mail cannot be edited without invalidating the signature. This means the electronic signature guarantees the integrity of the message, allowing verification that the content has not been altered after signing.
Authenticity
An electronic signature serves to verify the identity of the signer. Encryption technology is used, which allows proving that the person who signed the e-mail is indeed who they claim to be.
Non-repudiation
An electronic signature ensures that the signer cannot deny signing the e-mail. Thanks to encryption and certificate technology, it is possible to prove who signed the e-mail and when, which increases the trustworthiness of the communication.
AUTOMATION OF S/MIME
KeyTalk CKMS can automate the lifecycle of S/MIME certificates by ensuring their automatic creation, distribution, and renewal without the need for manual intervention. The system also manages their revocation, eliminating the risk of human errors and certificate expiration.

FAQ - frequently asked questions
What is an S/MIME certificate suitable for?
An S/MIME certificate is intended for the digital signature of emails in email clients. It also allows emails to be encrypted.
What types of S/MIME certificates do you sell?
We sell S/MIME certificates for guaranteed electronic signatures. We do not offer certificates for qualified signatures and have no plans to do so.
What is the difference between a guaranteed and a qualified signature?
A guaranteed electronic signature guarantees that the signature was created by the certificate owner. In the case of Class 2 certificates, it is also possible to verify their identity (name and organization).
A qualified signature is a signature of a higher level of trustworthiness. It requires the private key to be stored on a qualified device (token) and is therefore recognized for legal acts (the equivalent of a handwritten signature) and is also recognized by public administration (compliant with eIDAS).
Are these S/MIME certificates compliant with the eIDAS regulation?
The S/MIME certificates we offer are for guaranteed electronic signatures and therefore do not comply with the eIDAS regulation. We currently do not offer certificates for eIDAS.
