Resumo

JSch library has critical post-quantum cryptography vulnerabilities with 30 broken algorithm implementations and 165 quantum-vulnerable cryptographic primitives. The codebase extensively uses RSA, DSA, ECDSA, and legacy ciphers (3DES, Blowfish) that will be completely broken by quantum computers, creating significant long-term security and compliance risks. Immediate migration planning to NIST-approved post-quantum algorithms is essential for regulatory compliance and future-proofing.
