(Ruby) List Keys in a Microsoft Storage Provider

Demonstrates how to list the keys found in a Microsoft CNG Storage Provider, or a Legacy CryptoAPI Storage Provider.

Important: This example requires Chilkat v9.5.0.83 or greater.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

# This example requires Chilkat v9.5.0.83 or greater.

keyCon = Chilkat::CkKeyContainer.new()
json = Chilkat::CkJsonObject.new()
json.put_EmitCompact(false)

success = keyCon.GetKeys("Microsoft Software Key Storage Provider",json)
if (success != true)
    print keyCon.lastErrorText() + "\n";
    exit
end

print json.emit() + "\n";

# Sample JSON returned by GetKeys

# If the storage provider is CNG, then each key has an "algId".
# If the storage provider is legacy CryptoAPI, then each key has a "provType" (see below)

# If the storage provider is CNG:
# {
#   "storageProvider": "Microsoft Software Key Storage Provider",
#   "key": [
#     {
#       "name": "cn=Chilkat Admin,ou=Persona Not Verified,ou=For Test Purposes Only Decryption Key",
#       "machineKey": false,
#       "algId": "ECDH_P384"
#     },
#     {
#       "name": "CD1CC265-0DA0-4230-8419-CB6F808FE688",
#       "machineKey": false,
#       "algId": "SP800_108_CTR_HMAC"
#     },
#     {
#       "name": "{FF14487C-0AED-471E-8FAD-4BF757C2195C}",
#       "machineKey": false,
#       "algId": "ECDH_P256"
#     },
#     {
#       "name": "{869FD9A6-D815-44FD-A916-4D4A708CD949}",
#       "machineKey": false,

#       "machineKey": false,
#       "algId": "RSA"
#     },
#     {
#       "name": "Microsoft Connected Devices Platform device certificate",
#       "machineKey": false,
#       "algId": "ECDSA_P256"
#     }
#   ]
# }

# If the storage provider is legacy CryptoAPI:

# {
#   "storageProvider": "Microsoft Base Cryptographic Provider v1.0",
#   "key": [
#     {
#       "name": "{48D7FF88-A52E-41E2-9EBD-0CC7E880DC65}",
#       "machineKey": false,
#       "provType": "PROV_RSA_FULL"
#     },
#     {
#       "name": "{CBF7A33A-F9CF-4C30-8A06-94A5C7981058}",
#       "machineKey": false,
#       "provType": "PROV_RSA_FULL"
