!!! Overview
[{$pagename}], In [Public Key Infrastructure] ([PKI]) systems, a [{$pagename}] ([CSR]) is a message sent from an applicant to a [Certificate Authority] in order to apply for a digital identity [certificate].
The most common format for [CSRs] is the [PKCS #10|PKCS10] specification and another less common is the [Signed Public Key and Challenge] ([SPKAC]) format generated by some Web browsers.
!! CertificationRequestInfo
CertificationRequestInfo is an ASN.1 type that contains:
subject's
* [Distinguished Name]
* subject [Public Key]
* Optionally a set of attributes is constructed by an entity requesting certification.
This value is [Digitally Signed] by the subject's [Private Key] and CertificationRequestInfo and the [Digital Signature Algorithm] ID is sent to the [Certificate Authority]
Certification request information shall have [ASN.1] type CertificationRequestInfo:
{{{ CertificationRequestInfo ::= SEQUENCE {
version INTEGER { v1(0) } (v1,...),
subject Name,
subjectPKInfo SubjectPublicKeyInfo{{ PKInfoAlgorithms }},
attributes [0] Attributes{{ CRIAttributes }}
}
SubjectPublicKeyInfo { ALGORITHM : IOSet} ::= SEQUENCE {
algorithm AlgorithmIdentifier {{IOSet}},
subjectPublicKey BIT STRING
}
PKInfoAlgorithms ALGORITHM ::= {
... -- add any locally defined algorithms here -- }
Attributes { ATTRIBUTE:IOSet } ::= SET OF Attribute{{ IOSet }}
CRIAttributes ATTRIBUTE ::= {
... -- add any locally defined attributes here -- }
Attribute { ATTRIBUTE:IOSet } ::= SEQUENCE {
type ATTRIBUTE.&id({IOSet}),
values SET SIZE(1..MAX) OF ATTRIBUTE.&Type({IOSet}{@type})
}
}}}
