Kryptus key stores - Amplia

observação

Kryptus key stores are compatible with all supported platforms

To store keys on a Kryptus kNET HSM, use the following settings:

  • Type: Kryptus
  • Host: IP address or hostname of the VHSM
  • Port: HTTPS port of the VHSM (not the TTLV port)

If you intend to use the HSM for storing CA keys, set credentials for a regular user (not a VCO user) on the following settings:

  • RootUsername
  • RootPassword

If you intend to use the HSM for storing user PIN-protected keys (typically combined with Lacuna's PSC module), set the credentials for a VCO user (not a regular user) on the following settings:

  • VcoUsername
  • VcoPassword
observação

If you intend to use the same VHSM for both use cases, set all 4 settings. However, this would be very unusual, since it is recommended to keep CA and user keys in separate VHSMs.

Sample configuration (.ini or .conf file):

[KeyStores:MyKryptusHsm]
Type=Kryptus
Host=10.1.2.3
Port=50000
RootUsername=SOME_REGULAR_USER
RootPassword=SOME_PASSWORD
VcoUsername=SOME_VCO_USER
VcoPassword=SOME_PASSWORD

Sample configuration (environment variables):

KeyStores__MyKryptusHsm__Type=Kryptus
KeyStores__MyKryptusHsm__Host=10.1.2.3
KeyStores__MyKryptusHsm__Port=50000
KeyStores__MyKryptusHsm__RootUsername=SOME_REGULAR_USER
KeyStores__MyKryptusHsm__RootPassword=SOME_PASSWORD
KeyStores__MyKryptusHsm__VcoUsername=SOME_VCO_USER
KeyStores__MyKryptusHsm__VcoPassword=SOME_PASSWORD

Sample configuration (.json file):

"KeyStores": {
	"MyKryptusHsm": {
		"Type": "Kryptus",
		"Host": "10.1.2.3",
		"Port": 50000,
		"RootUsername": "SOME_REGULAR_USER",
		"RootPassword": "SOME_PASSWORD",
		"VcoUsername": "SOME_VCO_USER",
		"VcoPassword": "SOME_PASSWORD"
	}
}
observação

Please note that the Port value shown above is merely a sample. There is no default value for this setting. It depends entirely on your VHSM configuration.

Troubleshooting​

You might encounter the following error when using a Kryptus key store on Ubuntu 20.04:

System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.
---> System.Security.Authentication.AuthenticationException: Authentication failed, see inner exception.
---> Interop+OpenSsl+SslException: SSL Handshake failed with OpenSSL error - SSL_ERROR_SSL.
---> Interop+Crypto+OpenSslCryptographicException: error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure
    --- End of inner exception stack trace ---
    at Interop.OpenSsl.DoSslHandshake(SafeSslHandle context, ReadOnlySpan`1 input, Byte[]& sendBuf, Int32& sendCount)
    at System.Net.Security.SslStreamPal.HandshakeInternal(SafeFreeCredentials credential, SafeDeleteSslContext& context, ReadOnlySpan`1 inputBuffer, Byte[]& outputBptions sslAuthenticationOptions)
    --- End of inner exception stack trace ---
    at System.Net.Security.SslStream.ForceAuthenticationAsync[TIOAdapter](TIOAdapter adapter, Boolean receiveFirst, Byte[] reAuthenticationData, Boolean isApm)
    at System.Net.Http.ConnectHelper.EstablishSslConnectionAsync(SslClientAuthenticationOptions sslOptions, HttpRequestMessage request, Boolean async, Stream streamllationToken)
    --- End of inner exception stack trace ---
    at System.Net.Http.ConnectHelper.EstablishSslConnectionAsync(SslClientAuthenticationOptions sslOptions, HttpRequestMessage request, Boolean async, Stream streamllationToken)
    at System.Net.Http.HttpConnectionPool.ConnectAsync(HttpRequestMessage request, Boolean async, CancellationToken cancellationToken)
	...

In this case, edit the OpenSSL configuration file:

nano /etc/ssl/openssl.cnf

Add the following to the top of the file:

#
# This is part 1/2 of a workaround for SSL handshake issues with Kryptus HSMs, for more info
# see https://docs.lacunasoftware.com/articles/amplia/on-premises/key-stores/kryptus
#
openssl_conf = default_conf

Then, add the following to the bottom of the file:

#
# This is part 2/2 of a workaround for SSL handshake issues with Kryptus HSMs, for more info
# see https://docs.lacunasoftware.com/articles/amplia/on-premises/key-stores/kryptus
#
[default_conf]
ssl_conf = ssl_sect

[ssl_sect]
system_default = system_default_sect

[system_default_sect]
MinProtocol = TLSv1.2
CipherString = DEFAULT:@SECLEVEL=1

For more information, please refer to the related .NET runtime issue.
