Support in-place encryption in the cipher types, then use it on the plaintext packets
instead of allocating a new array each time. Removes 2 of 4 bytes allocated for each
byte uploaded over SFTP.
For AES-CTR, supporting in-place encryption in this case means adding a persistent buffer
for the keystream and encrypting in chunks. The performance difference is ~1-2% i.e.
marginal versus one-shotting it. The variance is similar also for different choices of
buffer size (here 4096 is used).
* Use System.Security.Cryptography in DesCipher and TripleDesCipher; Fall back to use BouncyCastle if BCL doesn't support
* Drop DesCipher; Replace PKCS7Padding with BouncyCastle's implementation.
* Restore `CbcCipherMode`
* Restore AesCipherMode; Use BlockImpl instead of BouncyCastleImpl for 3DES-CFB on lower targets.
* Restore the xml doc comment
* Preparation to enforce formatting and style in CI
- enabled IDE0055 to enforce formatting on build
- disabled SA1137 and SA1025 because they are already
covered by IDE0055
- disabled SA1021 because it conflicts with csharp_space_after_cast
* Cleanup formatting and style on codebase
This commit has no manual changes, it is the result
of running "dotnet format whitespace" and "dotnet format style"
* new formatting fixes after merge
* appveyor: set git autocrlf
as suggested by sharwell to hopefully fix Windows CI.
* use autocrlf input
to hopefully fix Linux tests
* fix formatting
* use autocrlf input for Linux only
* set csharp_space_after_cast to false
* Revert SA1021 suppression

This makes it easier to reason about Key instances in e.g.
DigitalSignature implementations, because we know that the
Key is initialised with its data and will not change.

* Add FEATURE_AES_CSP to use hardware-accelerated AesCryptoServiceProvider
Reduces CPU usage dramatically, allowing more performance on slower machines
* Restructure, move most of the feature code to AesCipher.cs
Fix padding for non-AES blockciphers
Fix IV exception for non-AES blockciphers
* Fix the AES Padding
It looks like the legacy code doesn't correctly remove padding, so this code needs to do the same.
* fix rebase issues
restructure AES CSP code into its own class
* Minor fixes
* Rework based on suggestions
* Move all changes to AesCypher.cs, as per Rob-Hague suggestion
Remove FEATURE_AES_CSP conditional
Fix OFB CipherMode
* update AesCipherTest.cs generator
* Fix continuous session encrypt/decrypt
(preserve IV between calls when Padding is None)
* Reduce CTR memory usage in Net 6+
Small performance increase in CTR buffer mode
Cosmetic changes
* Factor out the implementations and re-add the existing constructor
* remove ctor; revert tests; remove unused _iv member
* Reorder Encryption cipher preference list
* Remove redundant AES tests
Add tests for stream cipher state preservation
* Refactor ArrayXOR()
* Add test for IV overflow
* Performance bump for AES CTR (thanks @robhague)
* fix merge conflict
* Move AesCipherMode enum to its own file

* Move test projects to test folder.
Move global.json to root of repo.
Update solution items in solution.
* Move test projects to test folder.
Move global.json to root of repo.
Update solution items in solution.
Update appveyor configuration/
* Attempt to have appveyor use the correct .NET SDK.
* Update .NET SDK to version 7.0.402.
* Move Data folder below Renci.SshNet.Tests.
* Make csinst less chatty.
* Move Data folder directly below test folder as it's used by multiple test projects.
* Remove CS1591 nowarn from concrete test projects as this is already defined in the Directory.Build.props that is in the test folder.
* Fix integration test after moving test projects
