Providers

On current moment following providers are available out of the box:

• JDK - via JDK built-in JCA
• WebCrypto - via WebCrypto
• Apple - via CommonCrypto
• OpenSSL3 - via OpenSSL 3.x, statically linked to prebuilt OpenSSL 3.0.8 or dynamically linked (experimental)

Supported primitives

While the library is overall multiplatform and all algorithm/operation interfaces are available on all targets, support for a specific algorithm for a specific target depends on the used provider. Below there are several tables which show what is supported and what not (I know that it’s not the easiest thing to understand… But we have what we have).

For additional limitation please consult provider specific documentation.

Supported algorithms per provider

supported here means that those algorithms are tested and works at least in some configuration (f.e. different Java versions or Java providers can have different algorithms supported)
