Public bug reported: GPG is broken on RISC-V when vector length (VLEN) doesn't equal 128B.
This has been fixed upstream: https://github.com/gpg/libgcrypt/commit/3f684fc6ab3ac98320e245a06b3563ad37ec56f5 Test: head -c 10000 /dev/urandom > in.bin PW="testpw-correct-horse-battery-staple" gpg --batch --pinentry-mode loopback --passphrase "$PW" --yes --symmetric \ --cipher-algo AES256 --output out.gpg in.bin gpg --batch --pinentry-mode loopback --passphrase "$PW" --yes \ --decrypt --output dec.bin out.gpg if cmp -s in.bin dec.bin; then echo "PASS encrypt/decrypt" else echo "MISMATCH" fi Run this on x86 it works fine but run it on SpacemiT K3 with VLEN=256 it fails.
