CryptoPro CSP Packages — Customer-Provided

This directory is a placeholder for customer-provided CryptoPro CSP binaries.

Why Are Binaries Not Included?

CryptoPro CSP is commercial software licensed per-deployment by CryptoPro LLC (crypto-pro.ru). StellaOps cannot redistribute these binaries due to licensing restrictions.

Distribution Model:

StellaOps ships: Plugin interface code (AGPL-3.0-or-later) + documentation
Customer provides: Licensed CryptoPro CSP binaries + EULA acceptance

Installation

After placing your licensed bundle here:

# Set the EULA acceptance flag (only if you agree to CryptoPro's EULA)
export CRYPTOPRO_ACCEPT_EULA=1

# Run the installer script
./devops/services/cryptopro/install-linux-csp.sh

The installer will:

Auto-detect your host architecture
Extract the appropriate bundle
Install minimal required packages (CSP core + PKCS#11)

Plugin Initialization

Without valid CSP binaries installed, the CryptoPro plugin will NOT initialize.

The plugin performs runtime checks for CSP availability. If CSP is not installed or not licensed, the plugin will:

Log a warning about missing CSP
Return null from ICryptoProvider resolution
Fall back to alternative providers (if configured)
