What is a .P7C file?
The .P7C file extension represents a PKCS #7 Certificate File. This type of file is a digital certificate that is used by various software applications to confirm the identity of a website or web entity. It is similar to a .P7B file because both types contain a public key. This public key is essential for verifying the identity of an entity through a method known as public-key cryptography.
Public-key cryptography is a way to secure communications or verify identities using a pair of keys: a public key and a private key. The public key, which is what the .P7C file contains, can be shared with anyone. It is used to verify that a message or digital signature was created by the holder of the corresponding private key, ensuring the authenticity of the sender.
Several programs can open .P7C files, including: - Microsoft Certificate Manager: This is a tool included with the Windows operating system that allows users to manage digital certificates. It can import .P7C files to help authenticate web identities. - Microsoft Windows Contacts: Also included with the Windows operating system, this application can work with .P7C files as part of managing contact information and security. - Adobe Acrobat Reader DC and Adobe Acrobat DC: Both of these Adobe programs can open .P7C files. They are widely used for viewing, creating, and managing PDF documents, but they also support digital certificates to ensure the authenticity of PDF documents. - Apple Keychain Access: This is a macOS application included with the operating system. It manages passwords and digital certificates, allowing users to store and access them securely. It can import .P7C files to verify digital signatures and certificates.
Once a .P7C file has been imported into one of these programs, the software typically adds the verified entity to its list of trusted identities. This means that the program recognizes the digital certificate as valid and authentic, which helps in securing communications and verifying identities in digital transactions or interactions.
