AES is commonly accepted as a * strong cipher internationally, and is often hardware-accelerated. * Camellia also has wide international support across standards * organizations. SEED is only recommended by the Korean government. 3DES * only provides 112 bits of security. RC4 is now deprecated or forbidden * by many standards organizations. * * Within symmetric algorithm sections, order by message authentication * algorithm: GCM, then HMAC-SHA1, then HMAC-SHA256, then HMAC-MD5. * * Within message authentication algorithm sections, order by asymmetric * signature algorithm: ECDSA, then RSA, then DSS. * * Exception: Because some servers ignore the high-order byte of the cipher * suite ID, we must be careful about adding cipher suites with IDs larger * than 0x00ff; see bug 946147. For these broken servers, the first six cipher * suites, with the MSB zeroed, look like: * TLS_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA { 0x00,0x14 } * TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA { 0x00,0x13 } * TLS_KRB5_EXPORT_WITH_RC4_40_MD5 { 0x00,0x2B } * TLS_RSA_WITH_AES_128_CBC_SHA { 0x00,0x2F } * TLS_RSA_WITH_3DES_EDE_CBC_SHA { 0x00,0x0A } * TLS_RSA_WITH_DES_CBC_SHA { 0x00,0x09 } * The broken server only supports the fifth and sixth ones and will select * the fifth one. */ const PRUint16 SSL_ImplementedCiphers[] = { #ifdef NSS_ENABLE_ECC TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305, TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305, TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, /* TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA must appear before * TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA to work around bug 946147. */ TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_ECDSA_WITH_3DES_EDE_CBC_SHA, TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA, TLS_ECDHE_ECDSA_WITH_RC4_128_SHA, TLS_ECDHE_RSA_WITH_RC4_128_SHA, #endif /* NSS_ENABLE_ECC */ TLS_DHE_RSA_WITH_AES_128_GCM_SHA256, TLS_DHE_RSA_WITH_AES_128_CBC_SHA, TLS_DHE_DSS_WITH_AES_128_CBC_SHA, TLS_DHE_RSA_WITH_AES_128_CBC_SHA256, TLS_DHE_RSA_WITH_CAMELLIA_128_CBC_SHA, TLS_DHE_DSS_WITH_CAMELLIA_128_CBC_SHA, TLS_DHE_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_DSS_WITH_AES_256_CBC_SHA, TLS_DHE_RSA_WITH_AES_256_CBC_SHA256, TLS_DHE_RSA_WITH_CAMELLIA_256_CBC_SHA, TLS_DHE_DSS_WITH_CAMELLIA_256_CBC_SHA, SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA, SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA, TLS_DHE_DSS_WITH_RC4_128_SHA, #ifdef NSS_ENABLE_ECC TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDH_RSA_WITH_AES_128_CBC_SHA, TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDH_RSA_WITH_AES_256_CBC_SHA, TLS_ECDH_ECDSA_WITH_3DES_EDE_CBC_SHA, TLS_ECDH_RSA_WITH_3DES_EDE_CBC_SHA, TLS_ECDH_ECDSA_WITH_RC4_128_SHA, TLS_ECDH_RSA_WITH_RC4_128_SHA, #endif /* NSS_ENABLE_ECC */ TLS_RSA_WITH_AES_128_GCM_SHA256, TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_128_CBC_SHA256, TLS_RSA_WITH_CAMELLIA_128_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA256, TLS_RSA_WITH_CAMELLIA_256_CBC_SHA, TLS_RSA_WITH_SEED_CBC_SHA, SSL_RSA_FIPS_WITH_3DES_EDE_CBC_SHA, SSL_RSA_WITH_3DES_EDE_CBC_SHA, SSL_RSA_WITH_RC4_128_SHA, SSL_RSA_WITH_RC4_128_MD5, /* 56-bit DES "domestic" cipher suites */ SSL_DHE_RSA_WITH_DES_CBC_SHA, SSL_DHE_DSS_WITH_DES_CBC_SHA, SSL_RSA_FIPS_WITH_DES_CBC_SHA, SSL_RSA_WITH_DES_CBC_SHA, /* export ciphersuites with 1024-bit public key exchange keys */ TLS_RSA_EXPORT1024_WITH_RC4_56_SHA, TLS_RSA_EXPORT1024_WITH_DES_CBC_SHA, /* export ciphersuites with 512-bit public key exchange keys */ SSL_RSA_EXPORT_WITH_RC4_40_MD5, SSL_RSA_EXPORT_WITH_RC2_CBC_40_MD5, /* ciphersuites with no encryption */ #ifdef NSS_ENABLE_ECC TLS_ECDHE_ECDSA_WITH_NULL_SHA, TLS_ECDHE_RSA_WITH_NULL_SHA, TLS_ECDH_RSA_WITH_NULL_SHA, TLS_ECDH_ECDSA_WITH_NULL_SHA, #endif /* NSS_ENABLE_ECC */ SSL_RSA_WITH_NULL_SHA, TLS_RSA_WITH_NULL_SHA256, SSL_RSA_WITH_NULL_MD5, /* SSL2 cipher suites. */ SSL_EN_RC4_128_WITH_MD5, SSL_EN_RC2_128_CBC_WITH_MD5, SSL_EN_DES_192_EDE3_CBC_WITH_MD5, /* actually 112, not 192 */ SSL_EN_DES_64_CBC_WITH_MD5, SSL_EN_RC4_128_EXPORT40_WITH_MD5, SSL_EN_RC2_128_CBC_EXPORT40_WITH_MD5, 0 }; const PRUint16 SSL_NumImplementedCiphers = (sizeof SSL_ImplementedCiphers) / (sizeof SSL_ImplementedCiphers[0]) - 1; const PRUint16 * SSL_GetImplementedCiphers(void) { return SSL_ImplementedCiphers; } PRUint16 SSL_GetNumImplementedCiphers(void) { return SSL_NumImplementedCiphers; }
