This section briefly describes Erlang records derived from ASN.1 specifications used to handle public and private keys. The scope is to describe the data types of each component, not the semantics. For information on the semantics, refer to the relevant standards and RFCs.
Use the following include directive to get access to the records and constant macros described in the following sections:
-include_lib("public_key/include/public_key.hrl").
Common non-standard Erlang
data types used to describe the record fields in the
following sections are defined in the
RSA as defined by the PKCS-1 standard and
#'RSAPublicKey'{
modulus, % integer()
publicExponent % integer()
}.
#'RSAPrivateKey'{
version, % two-prime | multi
modulus, % integer()
publicExponent, % integer()
privateExponent, % integer()
prime1, % integer()
prime2, % integer()
exponent1, % integer()
exponent2, % integer()
coefficient, % integer()
otherPrimeInfos % [#OtherPrimeInfo{}] | asn1_NOVALUE
}.
#'OtherPrimeInfo'{
prime, % integer()
exponent, % integer()
coefficient % integer()
}.
The DSA as defined by the
#'DSAPrivateKey',{
version, % integer()
p, % integer()
q, % integer()
g, % integer()
y, % integer()
x % integer()
}.
#'Dss-Parms',{
p, % integer()
q, % integer()
g % integer()
}.
The Elliptic Curve (ECC) as defined by
#'ECPrivateKey'{
version, % integer()
privateKey, % binary()
parameters, % der_encoded() - {'EcpkParameters', #'ECParameters'{}} |
{'EcpkParameters', {namedCurve, oid()}} |
{'EcpkParameters', 'NULL'} % Inherited by CA
publicKey % bitstring()
}.
#'ECParameters'{
version, % integer()
fieldID, % #'FieldID'{}
curve, % #'Curve'{}
base, % binary()
order, % integer()
cofactor % integer()
}.
#'Curve'{
a, % binary()
b, % binary()
seed % bitstring() - optional
}.
#'FieldID'{
fieldType, % oid()
parameters % Depending on fieldType
}.
#'ECPoint'{
point % binary() - the public key
}.
