Compilation from source

Release compilation

# Via make (recommended)
make release

# Or directly with cargo
cargo build --release --target x86_64-unknown-linux-musl

The resulting binary is located at:

target/x86_64-unknown-linux-musl/release/ssh-frontiere

This is a static binary of approximately 1 MB, with no system dependency. It can be copied directly to any Linux x86_64 server.

Verification

# Check the binary type
file target/x86_64-unknown-linux-musl/release/ssh-frontiere
# ELF 64-bit LSB executable, x86-64, statically linked

# Check the size
ls -lh target/x86_64-unknown-linux-musl/release/ssh-frontiere
# ~1-2 MB

Debug compilation

For development:

make build
# or
cargo build

Tests

Before deploying, verify that tests pass:

# Unit and integration tests
make test

# Lints (formatting + clippy)
make lint

# Dependency audit
make audit

Auxiliary binary: proof

An auxiliary binary is included for computing authentication proofs:

cargo build --release --target x86_64-unknown-linux-musl --bin proof

This binary is useful for testing challenge-response authentication without implementing SHA-256 computation on the client side.
