Type conflict: 'PublicKeyFactory' exists in both BouncyCastle and iTextSharp"

[GentiSe]

A type conflict has been encountered in the project due to the PublicKeyFactory type being 'maybe' defined in both of the following assemblies:

• BouncyCastle.Crypto, Version=1.8.9.0, Culture=neutral, PublicKeyToken=0e99375e54769942
• itextsharp, Version=5.4.3.0, Culture=neutral, PublicKeyToken=8354ae6d2174ddca

⚠️ Note: I have not directly installed or referenced itextsharp in the project. Despite that, the build still reports a conflict involving it, which suggests it may be coming in transitively through another dependency.

This results in the following error during build or runtime:

The type 'PublicKeyFactory' exists in both 'BouncyCastle.Crypto, Version=1.8.9.0, Culture=neutral, PublicKeyToken=0e99375e54769942' and 'itextsharp, Version=5.4.3.0, Culture=neutral, PublicKeyToken=8354ae6d2174ddca'

Workarounds Attempted that worked.

• ✅ Package aliasing: I applied an alias to BouncyCastle.Crypto

I'm unclear what issue is being reported here. Yes, if your project brings in multiple jars with namespace conflicts then you typically need to use extern alias to resolve the ambiguities.
