OpenSSL.X509.Request

An interface to PKCS#10 certificate request.

Type

data X509Req

X509Req is an opaque object that represents PKCS#10 certificate request.

Functions to manipulate request

newX509Req :: IO X509Req

newX509Req creates an empty certificate request. You must set the following properties to and sign it (see signX509Req) to actually use the certificate request.

Version

See setVersion.

Subject Name

See setSubjectName.

Public Key

See setPublicKey.

signX509Req

Arguments

:: KeyPair key

=> X509Req

The request to be signed.

-> key

The private key to sign with.

-> Maybe Digest

A hashing algorithm to use. If Nothing the most suitable algorithm for the key is automatically used.

-> IO ()

signX509Req signs a certificate request with a subject private key.

verifyX509Req

Arguments

:: PublicKey key

=> X509Req

The request to be verified.

-> key

The public key to verify with.

-> IO VerifyStatus

verifyX509Req verifies a signature of certificate request with a subject public key.

printX509Req :: X509Req -> IO String

printX509Req req translates a certificate request into human-readable format.

writeX509ReqDER :: X509Req -> IO ByteString

writeX509ReqDER req writes a PKCS#10 certificate request to DER string.

makeX509FromReq :: X509Req -> X509 -> IO X509

makeX509FromReq req cert creates an empty X.509 certificate and copies as much data from the request as possible. The resulting certificate doesn't have the following data and it isn't signed so you must fill them and sign it yourself.

• Serial number
• Validity (Not Before and Not After)

Example:

import Data.Time.Clock

genCert :: X509 -> EvpPKey -> Integer -> Int -> X509Req -> IO X509
genCert caCert caKey serial days req
    = do cert <- makeX509FromReq req caCert
         now  <- getCurrentTime
         setSerialNumber cert serial
         setNotBefore cert $ addUTCTime (-1) now
         setNotAfter  cert $ addUTCTime (days * 24 * 60 * 60) now
         signX509 cert caKey Nothing
         return cert

Accessors

getVersion :: X509Req -> IO Int

getVersion req returns the version number of certificate request.

setVersion :: X509Req -> Int -> IO ()

setVersion req ver updates the version number of certificate request.

getSubjectName :: X509Req -> Bool -> IO [(String, String)]

getSubjectName req wantLongName returns the subject name of certificate request. See getSubjectName of OpenSSL.X509.

setSubjectName :: X509Req -> [(String, String)] -> IO ()

setSubjectName req name updates the subject name of certificate request. See setSubjectName of OpenSSL.X509.

getPublicKey :: X509Req -> IO SomePublicKey

getPublicKey req returns the public key of the subject of certificate request.

setPublicKey :: PublicKey key => X509Req -> key -> IO ()

setPublicKey req updates the public key of the subject of certificate request.

addExtensions :: X509Req -> [(Int, String)] -> IO CInt

addExtensions req [(nid, str)]

E.g., nid 85 = subjectAltName http://osxr.org:8080/openssl/source/crypto/objects/objects.h#0476
