To use eNULL ciphers you must set the security level to 0: $ openssl ciphers -s -tls1_2 -v eNULL:@SECLEVEL=0 ECDHE-ECDSA-NULL-SHA TLSv1 Kx=ECDH Au=ECDSA Enc=None Mac=SHA1 ECDHE-RSA-NULL-SHA TLSv1 Kx=ECDH Au=RSA Enc=None Mac=SHA1 AECDH-NULL-SHA TLSv1 Kx=ECDH Au=None Enc=None Mac=SHA1 NULL-SHA256 TLSv1.2 Kx=RSA Au=RSA Enc=None Mac=SHA256 NULL-SHA SSLv3 Kx=RSA Au=RSA Enc=None Mac=SHA1 NULL-MD5 SSLv3 Kx=RSA Au=RSA Enc=None Mac=MD5 -- Viktor. -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
