What is Public Key Infrastructure (PKI) Software for Microsoft Azure?

Public Key Infrastructure (PKI) software provides a framework for secure communications, managing digital certificates and encryption keys for data protection and identity verification. It enables organizations to authenticate users, devices, and applications, ensuring that only authorized entities can access sensitive information. PKI software supports encryption, enabling secure data exchange over networks by encrypting data with a public key that only a corresponding private key can decrypt. It also facilitates digital signatures, providing non-repudiation and ensuring data integrity by verifying that the data has not been altered. Overall, PKI software is essential for establishing trust in digital communications, especially in environments requiring high-security standards, such as government and financial institutions.

    KeyTalk

    KeyTalk

    KeyTalk

    KeyTalk is independent of Certificate Authorities and linked to a large number of public CAs both GMO GlobalSign and Digicert QuoVadis. Switching between CAs is simple and easy, even when thousands of certificates and end-points are involved. A vendor lock-in is therefore no longer the case. KeyTalk contains an internal CA for the generation of private certificates and keys. Did you use previously expensive public certificates for internal purposes? Or did you run into the limited functionality of Microsoft CS and other private CAs? Then, you will like our internal CA, private PKI certificate issuance. KeyTalk keeps track of the lifecycle of your certificates in a fully automated way. This way, you always have a complete and up to date overview of all your certificates, including the certificate name, SAN and validity. Also, things like used crypto keys and algorithms of internal and external certificates can be included.
