S/MIME Secure/Multipurpose Internet Mail data

A p10 file extension is related to the S/MIME Secure/Multipurpose Internet Mail files.

Further details

The p10 file extension is related to secured e-mail messages. 

S/MIME (Secure/Multipurpose Internet Mail Extensions) provides a consistent way to send and receive secure MIME data. Based on the popular Internet MIME standard, S/MIME provides the following cryptographic security services for electronic messaging applications: authentication, message integrity and non-repudiation of origin (using digital signatures) and privacy and data security (using encryption).

S/MIME can be used by traditional mail user agents (MUAs) to add cryptographic security services to mail that is sent, and to interpret cryptographic security services in mail that is received. However, S/MIME is not restricted to mail; it can be used with any transport mechanism that transports MIME data, such as HTTP. As such, S/MIME takes advantage of the object-based features of MIME and allows secure messages to be exchanged in mixed-transport systems.

Further, S/MIME can be used in automated message transfer agents that use cryptographic security services that do not require any human intervention, such as the signing of software-generated documents and the encryption of FAX messages sent over the Internet.

A typical application which allows a user to generate cryptographic information has to submit that information to a certification authority, who transforms it into a certificate. PKCS #10 describes a syntax for certification requests. The application/pkcs10 body type MUST be used to transfer a PKCS #10 certification request.

MIME types:
application/pkcs10
