Bug report: The rc4 input box is hard to understand for hex keys.

**Describe the bug**
I chose `hex` key provision in `rc4` encryption, but when I type `,` it doesn't match the result without the `,` separation

**To Reproduce**
Steps to reproduce the behaviour or a link to the recipe / input used to cause the bug:

1. Select `rc4` operation
2. Enter three identical hex values, `1f,10`, `1f10`, `0x1f,0x10`
3. Different values are output for the same input

**Expected behaviour**
Whatever form of `hex` I enter should represent the only hex content and output exactly the same result
