InOutBufReserved::get_out_len returns length of **input** buffer.

[dequbed]

Specifically this piece of code here:

utils/inout/src/reserved.rs

Lines 93 to 95 in 9d92d5e

	pub fn get_out_len(&self) -> usize {
	self.in_len
	}

I'm unsure if this is intended, but I can't figure out any use case where this is correct. The current implementation is an issue when the output buffer does need to be oversized because e.g. padding to block size is added, and some code checks for this oversized attribute using the mentioned method.

You can work around this issue by writing

buf.get_out().len();

instead of

buf.get_out_len();

but this is obviously less ergonomic.

Oh... It's certainly a bug. We probably should create a backport for inout v0.1.

Reopened until the v0.1 backport is merged and published.
