TLS Cipher Strength Checker

Analyze and audit cryptographic cipher suites against modern security standards.

Enter Cipher Suite String:

Supports OpenSSL (e.g., ECDHE-RSA-AES256-GCM-SHA384) and IANA (e.g., TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384) formats.

Cipher Suite	Rating	Issues Found

This tool evaluates cipher suites based on modern cryptographic best practices (NIST, Mozilla Security recommendations).

Primitive	Status	Algorithms
Protocol	Secure	TLS 1.2, TLS 1.3
	Insecure	SSLv2, SSLv3, TLS 1.0, TLS 1.1
Key Exchange	Strong	ECDHE, DHE (Forward Secrecy)
	Weak	RSA (No Forward Secrecy), DH (Static)
Encryption	Secure	AES-GCM, CHACHA20-POLY1305
	Moderate	AES-CBC (Legacy, requires heavy padding)
	Insecure	RC4, DES, 3DES, NULL, EXPORT
MAC/Hash	Secure	SHA256, SHA384, AEAD (Implicit)
	Insecure	MD5, SHA1
