imports wolfcrypt libraries

[datnguyentien1981]

Dear Nihal

Currently, I have an issue related to wolfcrypt libraries when I compile Rustboot on native ubuntu.

home@home:~/Prj_Security/SourceCode/rustBoot-main/rustBoot$ rustup override set nightly
info: using existing install for 'nightly-x86_64-unknown-linux-gnu'
info: override toolchain for '/home/home/Prj_Security/SourceCode/rustBoot-main/rustBoot' set to 'nightly-x86_64-unknown-linux-gnu'
nightly-x86_64-unknown-linux-gnu unchanged - rustc 1.59.0-nightly (f8abed9ed 2021-12-26)

As your recommendation in previous topic, I try to install wolfCrypt with below command pip install wolfcrypt but issue occurs as below

home@home:~/Prj_Security/SourceCode/rustBoot-main/rustBoot$ pip install wolfcrypt
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: wolfcrypt in /home/home/.local/lib/python3.6/site-packages (4.1.0.post0)
Requirement already satisfied: cffi in /home/home/.local/lib/python3.6/site-packages (from wolfcrypt) (1.15.0)
Requirement already satisfied: pycparser in /home/home/.local/lib/python3.6/site-packages (from cffi->wolfcrypt) (2.21)

I try to work around with another command https://github.com/wolfSSL/wolfBoot/blob/master/docs/Signing.md#install-python3

git clone https://github.com/wolfSSL/wolfssl.git
cd wolfssl
./configure --enable-keygen --enable-rsa --enable-ecc --enable-ed25519 --enable-ed448 --enable-des3 CFLAGS="-DWOLFSSL_PUBLIC_MP"
sudo make install

and issue occurs as below

home@home:~/Prj_Security/SourceCode/rustBoot-main/rustBoot/wolfssl$ ./configure --enable-keygen --enable-rsa --enable-ecc --enable-ed25519 --enable-ed448 --enable-des3 CFLAGS="-DWOLFSSL_PUBLIC_MP"

Could you please support me fix issue related to wolfcrypt libraries

Thank you

Can you try importing wolfcrypt from the python repl? I think you have a path issue of some sort.

[datnguyentien1981]

Thank you for your support. after I fix path issue, I can install wolfcrypt with below command

pip install wolfcrypt

nad6hc@VM-NAD6HC-OSD5:~/Prj_Security/SourceCode/rustBoot-main/rustBoot$ pip install wolfcrypt
