Added method to DaprClient and GRPC implementation to call cryptography proto endpoints

First pass at implementing all exposed Cryptography methods on Go interface
WhitWaldo
committed
Added examples for Cryptography block
WhitWaldo
committed
Added missing copyright statements
WhitWaldo
committed
Updated to properly support Crypto API this time
WhitWaldo
committed
Added copyright statements
WhitWaldo
committed
Removed deprecated examples as the subtle APIs are presently disabled
WhitWaldo
committed
Updated example to reflect new API shape
WhitWaldo
committed
Updated example and readme
WhitWaldo
committed
Added overloads for encrypting/decrypting streams instead of just fixed byte arrays. Added example demonstrating the same encrypting a file via a FileStream and decrypting from a MemoryStream.
WhitWaldo
committed
Added some unit tests to pair with the implementation
WhitWaldo
committed
Added null check for the stream argument
WhitWaldo
committed
Changed case of the arguments as they should read "plaintext" and not "plainText"
WhitWaldo
committed
Reduced number of encryption implementations by just wrapping byte array into memory stream
WhitWaldo
committed
Constrainted returned member types per review suggestion
WhitWaldo
committed
Updated methods to use ReadOnlyMemory<byte> instead of byte[] - updated implementations to use low-allocation spans where possible (though ToArray is necessary to wrap with MemoryStream).
WhitWaldo
committed
Updated to use encryption/decryption options instead of lots of method overload variations. Simplified gRPC implementation to use fewer methods. Applied argument name updates applied previously (pl…
WhitWaldo
committed
Updated tests
WhitWaldo
committed
Removed unused reference
WhitWaldo
committed
Updated examples to reflect new method shapes. Downgraded package to .net 6 instead of .net 8 per review suggestion.
WhitWaldo
committed
Updated to reflect non-aliased values per review suggestion
WhitWaldo
committed
Update to ensure that both send/receive streams run at the same time instead of sequentially.
WhitWaldo
committed
Updated to support streamed results in addition to fixed byte arrays. Refactored implementation to minimize duplicative code.
WhitWaldo
committed
Updated example to fix compile issue
WhitWaldo
committed
Removed encrypt/decrypt methods that accepted streams and returned ReadOnlyMemory<byte>. Marked implementations that use this on the gRPC class as private instead.
WhitWaldo
committed
Added missing Obsolete attributes on Encrypt/Decrypt methods. Added overloads on decrypt methods that do not require a DecryptionOptions to be passed in.
WhitWaldo
committed
Updated encrypt/decrypt options so the streaming block size no longer uses a uint. Added validation in its place to ensure the value provided is never less than or equal to 0.
WhitWaldo
committed
Updated how validation works in the options to accommodate lack of the shorter variation in .NET 6
WhitWaldo
committed
Updated names of encrypt/decrypt streaming methods so everything uses just EncryptAsync or DecryptAsync
WhitWaldo
committed
Fixed regression that would have prevented data from being sent entirely to the sidecar. Also simplified operation per suggestion in review.
WhitWaldo
committed
Updated examples to reflect changed API
WhitWaldo
committed
Updated so IAsyncEnumerable methods (encrypt and decrypt) return IAsyncEnumerable<ReadOnlyMemory<byte>> instead of IAsyncEnumerable<byte[]>.
WhitWaldo
committed
Updated example to reflect change from IAsyncEnumerable<byte> to IAsyncEnumerable<ReadOnlyMemory<byte>>
WhitWaldo
committed
Avoiding allocation by using MemoryMarshal instead of .ToArray() to create MemoryStream from ReadOnlyMemory<byte>.
WhitWaldo
committed
Performance updates to minimize unnecessary byte array copies and eliminate unnecessary allocations.
WhitWaldo
committed
Removed unnecessary return from SendPlaintextStreamAsync and SendCiphertextStreamAsync methods
WhitWaldo
committed
Updated exception text to be more specific as to what's wrong with the input value.
WhitWaldo
committed
Minor tweak to prefer using using a Memory
WhitWaldo
committed
Deduplicated some of the Decrypt methods, simplifying the implementation
WhitWaldo
committed
Eliminated duplicate encryption method, simplifying implementation
WhitWaldo
committed
Updated to eliminate an unnecessary `await` and `async foreach`.
WhitWaldo
committed
Updated stream example to reflect the changes to the API shape
WhitWaldo
committed
Added notes about operations with stream-based data
