[Breaking change]: RSA.EncryptValue and RSA.DecryptValue are obsolete #31614
Description
Description
RSA.EncryptValue and RSA.DecryptValue are obsolete with the SYSLIB0048 diagnostic code.
This obsoletion is for .NET 8 Preview 1.
Version
Other (please put exact version in description textbox)
Previous behavior
Callers could use RSA.EncryptValue or RSA.EncryptValue without a warning.
New behavior
In .NET 8, users of RSA.EncryptValue or RSA.EncryptValue will get a SYSLIB0048 compilation warning.
Type of breaking change
- Binary incompatible: Existing binaries may encounter a breaking change in behavior, such as failure to load/execute or different run-time behavior.
- Source incompatible: Source code may encounter a breaking change in behavior when targeting the new runtime/component/SDK, such as compile errors or different run-time behavior.
Reason for change
These APIs were never implemented and always produced a NotSupportedException. Their purpose is unclear and should not be used.
Recommended action
Callers that want to encrypt or decrypt with RSA should use Encrypt or Decrypt instead.
