    en.wikipedia.org/wiki/PKCS_12

    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 .

    .cer, .crt, .der – Distinguished Encoding Rules stores certificates.p7b, .p7c – PKCS#7 SignedData commonly appears without main data, just certificates or certificate revocation lists (CRLs).p12, .pfx – PKCS#12 can store public certificates and private keys

  4. PKCS - Wikipedia

    en.wikipedia.org/wiki/PKCS

    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.

    X.509 public key certificates, X.509 CRLs In cryptography , PKCS #7 ("PKCS #7: Cryptographic Message Syntax", "CMS") is a standard syntax for storing signed and/or encrypted data. PKCS #7 is one of the family of standards called Public-Key Cryptography Standards ( PKCS ) created by RSA Laboratories .

  6. Certificate-based encryption - Wikipedia

    en.wikipedia.org/wiki/Certificate-based_encryption

    Certificate-based encryption is a system in which a certificate authority uses ID-based cryptography to produce a certificate. This system gives the users both implicit and explicit certification, the certificate can be used as a conventional certificate (for signatures, etc.), but also implicitly for the purpose of encryption.

  7. Automatic Certificate Management Environment - Wikipedia

    The ISRG provides free and open-source reference implementations for ACME: certbot is a Python-based implementation of server certificate management software using the ACME protocol, [6] [7] [8] and boulder is a certificate authority implementation, written in Go. [9] Since 2015 a large variety of client options have appeared for all operating ...

  8. Authorization certificate - Wikipedia

    en.wikipedia.org/wiki/Authorization_certificate

    The authorization certificate works in conjunction with a public key certificate (PKC). While the PKC is issued by a certificate authority (CA) and is used as a proof of identity of its holder like a passport, the authorization certificate is issued by an attribute authority (AA) and is used to characterize or entitle its holder like a visa ...

  9. Privacy-Enhanced Mail - Wikipedia

    en.wikipedia.org/wiki/Privacy-Enhanced_Mail

    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.
