Fixes #13441 We're also starting on a glossary, doc/man7/openssl-glossary.pod, where terms we use should be explained. There's no need to explain terms as essays, but at least a few quick lines, and possibly a reference to some external documentation.

=item ASN.1, ASN1
|
|
|
|
ASN.1 ("Abstract Syntax Notation One") is a notation for describing abstract
|
|
types and values. It is defined in the ITU-T documents X.680 to X.683:
|
|
|
|
L<https://www.itu.int/rec/T-REC-X.680>,
|
|
L<https://www.itu.int/rec/T-REC-X.681>,
|
|
L<https://www.itu.int/rec/T-REC-X.682>,
|
|
L<https://www.itu.int/rec/T-REC-X.683>
|
|
|
|
=item DER ("Distinguished Encoding Rules")
|
|
|
|
DER is a binary encoding of data, structured according to an ASN.1
|
|
specification. This is a common encoding used for cryptographic objects
|
|
such as private and public keys, certificates, CRLs, ...
|
|
|
|
It is defined in ITU-T document X.690:
|
|
|
|
L<https://www.itu.int/rec/T-REC-X.690>
|
|
|
|
=item MSBLOB
|
|
|
|
MSBLOB is a Microsoft specific binary format for RSA and DSA keys, both
|
|
private and public. This form is never passphrase protected.
|
|
|
|
=item PEM ("Privacy Enhanced Message")
|
|
|
|
PEM is a format used for encoding of binary content into a mail and ASCII
|
|
friendly form. The content is a series of base64-encoded lines, surrounded
|
|
by begin/end markers each on their own line. For example:
|
|
|
|
-----BEGIN PRIVATE KEY-----
|
|
MIICdg....
|
|
... bhTQ==
|
|
-----END PRIVATE KEY-----
|
|
|
|
Optional header line(s) may appear after the begin line, and their existence
|
|
depends on the type of object being written or read.
|
|
|
|
For all OpenSSL uses, the binary content is expected to be a DER encoded
|
|
structure.
|
|
|
|
This is defined in IETF RFC 1421:
|
|
|
|
L<https://tools.ietf.org/html/rfc1421>
|
|
|
|
=item PKCS#8 (also known as "pkcs8" in some parts of OpenSSL)
|
|
|
|
PKCS#8 is a specification of an ASN.1 structure that OpenSSL uses for
|
|
storing or transmitting any private key in a key type agnostic manner, and
|
|
has both an unencrypted and an encrypted form.
|
|
|
|
This is specified in RFC 5208:
|
|
|
|
L<https://tools.ietf.org/html/rfc5208>
|
|
|
|
=item PVK
|
|
|
|
PVK is a Microsoft specific binary format for RSA and DSA private keys.
|
|
This form may be passphrase protected.
|
|
|
|
=item SubjectPublicKeyInfo
|
|
|
|
SubjectPublicKeyInfo is an ASN.1 structure that OpenSSL uses for storing and
|
|
transmitting any public key in a key type agnostic manner.
|
|
|
|
This is specified as part of the specification for certificates, RFC 5280:
|
|
|
|
L<https://tools.ietf.org/html/rfc5280>
