I don't know which intentions have the developers of cryptography extensions about funct3-field and my proposal might won't fit in these intentions. To my mind 28-th bit can be used...

Yes, the descriptions for zip and unzip have to be swapped in a general sense. (UNZIP operation in spec is described as "inverse zip").

And I would like to clarify about **rev8** and **brev8** descriptions. Are these descriptions same? rev8: foreach (i from 0 to (xlen - 8) by 8) brev8: foreach (i from...

Okey, thank you for explanation!

@ben-marshall Okey :) I compared these descriptions of the instructions with old descriptions from bitmanip spec (v0.93).

Okay, you are welcome.

@ben-marshall Hi! I have a new question about encoding of _**zip/unzip**_ insns. In current scalar cryptography spec ZIP and UNZIP insns have different values in 20th bit. I understand the...

Yes, the encoding of **_zip/unzip_** (rv32 only) insns should look like below: 0000100 01111 rs 001 rd 0010011 -> **_zip_** 0000100 01111 rs 101 rd 0010011 - > **_unzip_**

Okey, happy to help!

Yes, the descriptions of zip/unzip operations in crypto spec v1.0.0-rc2 were correct. I'm sorry.
