RSA Encryption C#

wish help you to fix your issue Indeed, RSA is a deterministic encryption algorithm, so given the same keys and plaintext, the same cryptotext will be outputted. RSA is commonly used with a padding scheme to be semantically secure.
This is of course only the general case. I can't vouch for the RSACryptoServiceProvider in C#

Are there valid reasons for using a hardware encryption device (e.g. USB encryption dongle/keystore) over using a softwa

it helps some times It's not about what's more secure because nothing is 100% bullet proof. It's a question on "how to make it as difficult as possible"
You could see it from this point: If you store keys on the computer, they're there 24/7. If my pair of keys is on an external device, the keys are only accessible while attached to the device. ==> You reduce the timeframe in which somebody else can copy your keys. It's much easier to access something if physical access is not needed.

Does Spring Security Saml 2.0 support Assertion Level Encryption and AES-256 as Encryption Algorithm?

hop of those help? Yes, Spring SAML is able to receive SAML messages encrypted using AES-256 (http://www.w3.org/2001/04/xmlenc#aes256-cbc) by default. But it is not possible to configure Spring SAML to encrypt messages sent to IDP.

What kind of encryption is used by IBM graph? Both for encryption at rest and encryption at transit? LUKS, SSL or others

may help you . IBM Graph's client-facing APIs are only available via HTTPS w/ modern TLS versions. On the backend, data at rest is encrypted via LUKS, and data in motion is encrypted via TLS.

Is it possible to change a BigQuery table encryption from default to CMEK encryption via the API/Client Library

I think the issue was by ths following , You can essentially change to KMS protection in place by copying a table on to itself. In the relevant python example, you should set the dest_dataset_ref and dest_table_ref to be the same as the source ones and then configure the copy job to have WRITE_TRUNCATE write disposition, adding the following line: job_config.write_disposition = 'WRITE_TRUNCATE'
To do the same via REST API, run:

code :

alias gcurl='curl -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" -H "Content-Type: application/json" '

gcurl -X POST -T "kms_request.json" https://www.googleapis.com/bigquery/v2/projects/$PROJECT/jobs

{
"configuration": {
  "jobType": "COPY",
  "copy": {
   "sourceTable": {
    "projectId": "[PROJECT]",
    "datasetId": "[DATASET]",
    "tableId": "[TABLE]"
   },
   "destinationTable": {
    "projectId": "[PROJECT]",
    "datasetId": "[DATASET]",
    "tableId": "[TABLE]"
   },
   "writeDisposition": "WRITE_TRUNCATE",
   "destinationEncryptionConfiguration": {
   "kmsKeyName": "projects/[PROJECT]/locations/[KMS_KEY_LOCATION]/keyRings/[KMS_KEY_RING]/cryptoKeys/[KMS_KEY]"
   }
  }
 }
}

Software tools to automatically decrypt a file, whose encryption algorithm (and/or encryption keys) isn't known?

I hope this helps . If you've written your own "novel" encryption, without any "industry standard encryption techniques", and you don't know how to test it (ie: you are not an expert cryptographer), then I can already tell you the result.
Your scheme is hopelessly flawed, and can be broken by even undergraduate level cryptographers. Not that your scheme will ever encrypt anything so valuable as to be worth the time to crack.
