Summary

JSch repository has critical quantum-vulnerability exposure with widespread use of quantum-vulnerable algorithms including RSA, ECDSA, and legacy ciphers like 3DES and Blowfish. The library's core SSH implementation relies entirely on classical cryptography that will be broken by quantum computers, affecting all 33 vulnerable files with 206 total findings. Immediate migration planning to post-quantum cryptography is essential for long-term security compliance.
