The extension CRT is employed for certificates, with CER and CRT being almost interchangeable. This is especially prevalent in *nix systems. A file with a .crt extension encompasses an end-entity certificate, its public key, and identity details such as domain names verified to be linked with the certificate.
CRT certificates play a crucial role in enabling secure TLS handshakes, substantiating website identity ownership to browsers, and establishing encrypted sessions that are shielded against eavesdropping and content tampering.
A file bearing the '.p12' extension is a security key file associated with the Simple Order API. This extension signifies that the file adheres to the PKCS #12 standard, a part of the Public-Key Cryptography Standards (PKCS) established by RSA Laboratories. Functioning as an archive, a P12 file encompasses all essential cryptographic components.
Within a P12 file, one finds the private key, the public certificate from the Certificate Authority, and all intermediate certificates employed for signing. Notably, a P12 file can include a maximum of 10 intermediate certificates. These files play a pivotal role in securing communications between two applications and serve as a repository for digital certificates, including SSL certificates.
Creating a P12 file involves utilizing tools like OpenSSL, an open-source implementation of the SSL and TLS protocols. Once generated, the P12 file can be employed for securing communications or storing digital certificates.
To secure communications, the P12 file must be installed on both client and server machines. The client uses the P12 file to generate private and public keys, while the server verifies the client's identity using the public key. Alternatively, for storing digital certificates, saving the P12 file to a secure location suffices. Additionally, key management tools can be employed for efficient P12 file management.
P12 files emerge as a secure and practical solution for storing and utilizing digital certificates. They offer a convenient means of ensuring secure communication between applications.
