This module provides decoding of PKIX certificates either provided as files or as binaries.
decode_cert(Bin) -> {ok, Cert} | {error, Reason}
decode_cert(Bin, Opts) -> {ok, Cert} | {error, Reason}
Types:
Bin = binary()
Opts = [pkix | ssl | subject]
Cert = term()
decode_cert(Bin) is equivalent to
decode_cert(Bin, []).
The form of the returned certificate depends on the options.
If the options list is empty the certificate is returned as
a DER encoded binary, i.e. {ok, Bin} is returned,
where Bin> is the provided input.
The options pkix and ssl imply that the
certificate is returned as a parsed ASN.1 structure in the
form of an Erlang term.
The ssl option gives a more elaborate return
structure, with more explicit information. In particular
object identifiers are replaced by atoms.
The options pkix, and ssl are mutually
exclusive.
The option subject implies that only the subject's
distinguished name part of the certificate is returned. It
can only be used together with the option pkix or the
option ssl.
decode_cert_file(File) -> {ok, Cert} | {error, Reason}
decode_cert_file(File, Opts) -> {ok, Cert} | {error, Reason}
Types:
File = path()
Opts = [pem | pkix | ssl | subject]
Cert = term()
decode_cert_file(File) is equivalent to
decode_cert_file(File, []).
The form of the returned certificate depends on the options.
If the options list is empty the certificate is returned as
a DER encoded binary, i.e. the contents of the input
File is returned as a binary.
The options pkix and ssl implies that the
certificate is returned as a parsed ASN.1 structure in the
form of an Erlang term.
The ssl option gives a more elaborate return
structure, with more explicit information. In particular
object identifiers are replaced by atoms.
The options pkix, and ssl are mutually
exclusive.
The option subject implies that only the subject's
distinguished name part of the peer certificate is returned.
It can only be used together with the option pkix or
the option ssl.
