.NET Libraries in .NET 10 Preview 2 - Release Notes

Here's a summary of what's new in .NET Libraries in this preview release:

.NET Libraries updates in .NET 10:

Encryption algorithm can now be specified in PKCS#12/PFX Export

The new ExportPkcs12 methods on X509Certificate2 allow callers to choose what encryption and digest algorithms are used to produce the output. Pkcs12ExportPbeParameters.Pkcs12TripleDesSha1 indicates the Windows XP-era de facto standard, which produces an output supported by almost every library/platform that supports reading PKCS#12/PFX by choosing an older encryption algorithm. Pkcs12ExportPbeParameters.Pbes2Aes256Sha256 indicates that AES should be used instead of 3DES (and SHA-2-256 instead of SHA-1), but the output may not be understood by all readers (sorry, Windows XP).

Callers who want even more control can instead utilize the overload that accepts a PbeParameters.
