Microsoft PFX file format In cryptography , PKCS #12 defines an archive file format for storing many cryptography objects as a single file. It is commonly used to bundle a private key with its X.509 certificate or to bundle all the members of a chain of trust .
A user Alice can doubly encrypt a message using another user's (Bob) public key and his (Bob's) identity.. This means that the user (Bob) cannot decrypt it without a currently valid certificate and also that the certificate authority cannot decrypt the message as they don't have the user's private key (i.e., there is no implicit escrow as with ID-based cryptography, as the double encryption ...
Windows uses the .p7b file name extension [6] for both these encodings. A typical use of a PKCS #7 file would be to store certificates and/or certificate revocation lists (CRL). Here's an example of how to first download a certificate, then wrap it inside a PKCS #7 archive and then read from that archive:
See RFC 7292. Defines a file format commonly used to store private keys with accompanying public key certificates, protected with a password-based symmetric key. PFX is a predecessor to PKCS #12. This container format can contain multiple embedded objects, such as multiple certificates. Usually protected/encrypted with a password.
.p12, .pfx, .pkcs12 – PKCS#12, may contain certificate(s) (public) and private keys (password protected) in a single file. .pfx – Personal Information eXchange PFX, predecessor of PKCS#12 (usually contains data in PKCS#12 format, e.g. with PFX files generated in IIS)..crl – A Certificate Revocation List (CRL). Certificate Authorities ...
PEM data is commonly stored in files with a ".pem" suffix, a ".cer" or ".crt" suffix (for certificates), or a ".key" suffix (for public or private keys). [3] The label inside a PEM file represents the type of the data more accurately than the file suffix, since many different types of data can be saved in a ".pem" file.
The first part, ASN.1 type CertificationRequestInfo, consists of a version number (which is 0 for all known versions, 1.0, 1.5, and 1.7 of the specifications), the subject name, the public key (algorithm identifier + bit string), and a collection of attributes providing additional information about the subject of the certificate. The attributes ...
The architecture of CMS is built around certificate-based key management, such as the profile defined by the PKIX working group. CMS is used as the key cryptographic component of many other cryptographic standards, such as S/MIME , PKCS #12 and the RFC 3161 digital timestamping protocol.
