For information on accessibility improvements in. NET Framework 4.8, see What's new in accessibility in. NET Framework, managed cryptographic provider classes such as SHA256Managed throw a CryptographicException when the system cryptographic libraries are configured in "FIPS mode". These exceptions are thrown because the managed versions of the cryptographic provider classes, unlike the system cryptographic libraries, have not undergone FIPS (Federal Information Processing Standards) 140-2 certification. NET Framework 4.8, the following managed cryptography classes no longer throw a CryptographicException in this case: Because few developers have their development machines in FIPS mode, the exceptions are commonly thrown in production systems.īy default in applications that target. Instead, these classes redirect cryptographic operations to a system cryptography library. This change effectively removes a potentially confusing difference between developer environments and production environments and makes native components and managed components operate under the same cryptographic policy. Applications that depend on these exceptions can restore the previous behavior by setting the AppContext switch. For more information, see Managed cryptography classes do not throw a CryptographyException in FIPS mode. NET Framework 4.5, the clrcompression.dll assembly uses ZLib, a native external library for data compression, in order to provide an implementation for the deflate algorithm. NET Framework 4.8 version of clrcompression.dll is updated to use ZLib Version 1.2.11, which includes several key improvements and fixes.
