DESCRIPTION

This function wraps [Kestrun.Certificates.CertificateManager]::CreateSelfSignedCertificateFromJwk() and converts an RSA JWK into a self-signed X509Certificate2 instance.

The input can be:

  • a JWK JSON string, or
  • a PowerShell hashtable/PSCustomObject that will be serialized to JSON via ConvertTo-Json -Compress.

Once you have the certificate, you can export it to PFX/PEM using Export-KrCertificate.

EXAMPLES

EXAMPLE 1

$jwk = @{ kty = ‘RSA’ n = ‘…’ e = ‘AQAB’ d = ‘…’ p = ‘…’ q = ‘…’ dp = ‘…’ dq = ‘…’ qi = ‘…’ }

$cert = ConvertFrom-KrJwkJsonToCertificate -Jwk $jwk

EXAMPLE 2

$jwkJson = Get-Content ‘./client.jwk.json’ -Raw $cert = ConvertFrom-KrJwkJsonToCertificate -Jwk $jwkJson -SubjectName ‘CN=client-assertion’

EXAMPLE 3

$jwk = Get-Content ‘./client.jwk.json’ -Raw ConvertFrom-KrJwkJsonToCertificate -Jwk $jwk | Export-KrCertificate -FilePath ‘./certs/client’ -Format Pem -IncludePrivateKey

PARAMETERS

-Jwk

The JWK representation. Can be:

  • a JSON string, or
  • a hashtable / PSCustomObject with JWK fields (kty, n, e, d, p, q, dp, dq, qi, kid).
