To be precise it happens here:
CipherSupplier.class
cipher.init(ciphermode, key, params);
return cipher;
} catch (InvalidKeyException var6) {
Caused by: java.security.InvalidKeyException: Illegal key size

at javax.crypto.Cipher.implInit(Cipher.java:805)

key size is 32 bytes (256bits) though. Verified in the debugger.
from cli.
Okay this is an issue Oracle Java not supporting AES-256 by default. I assume the GUI used a different JVM.
One needs these files

Afterwards the Oracle JVM has 256 bit AES support. Should be mentioned somewhere I assume but is actually no bug in Cryptomator.
And it is actually mentioned. Sometime reading the Docs just helps. But could terminate with a nice message I assume ;)
from cli.
There would actually be a different exception, if we updated CryptoLib in the CLI project :D
