Create JWK Set Containing Certificates

See more Certificates Examples

Demonstrates how to create a JWK Set containing N certificates. AutoIt

Local $bSuccess = False

;  This example creates the following JWK Set from two certificates:

;  {
;    "keys": [
;      {
;        "kty": "RSA",
;        "use": "sig",
;        "kid": "BB8CeFVqyaGrGNuehJIiL4dfjzw",
;        "x5t": "BB8CeFVqyaGrGNuehJIiL4dfjzw",
;        "n": "nYf1jpn7cFdQ...9Iw",
;        "e": "AQAB",
;        "x5c": [
;          "MIIDBTCCAe2...Z+NTZo"
;        ]
;      },
;      {
;        "kty": "RSA",
;        "use": "sig",
;        "kid": "M6pX7RHoraLsprfJeRCjSxuURhc",
;        "x5t": "M6pX7RHoraLsprfJeRCjSxuURhc",
;        "n": "xHScZMPo8F...EO4QQ",
;        "e": "AQAB",
;        "x5c": [
;          "MIIC8TCCAdmgA...Vt5432GA=="
;        ]
;      }
;    ]
;  }

;  First get two certificates from files.
$oCert1 = ObjCreate("Chilkat.Cert")

;  We'll need this crypt object re-encode the SHA1 thumbprint from hex to base64.

$oJson.UpdateString("keys[i].use","sig")

$oJson.UpdateString("keys[i].kid",$sBase64Thumbprint)
$oJson.UpdateString("keys[i].x5t",$sBase64Thumbprint)

;  (We're assuming these are RSA certificates)
;  To get the modulus (n) and exponent (e), we need to get the cert's public key and then get its JWK.

;  Now add the entire X.509 certificate 
$oJson.UpdateString("keys[i].x5c[0]",$oCert1.GetEncoded())

;  Now do the same for cert2..
$oJson.I = 1

$oJson.UpdateString("keys[i].kty","RSA")

;  Now add the entire X.509 certificate 
$oJson.UpdateString("keys[i].x5c[0]",$oCert2.GetEncoded())

;  Emit the JSON..
