Subject: Remove experimental 56bit export ciphers
X-Git-Tag: OpenSSL_1_1_0-pre1~1589
X-Git-Url: https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff_plain;h=a258afaf7c0da143f15e1cf636279c7aaee7394f

Remove experimental 56bit export ciphers

These ciphers are removed:
    TLS1_CK_RSA_EXPORT1024_WITH_RC4_56_MD5
    TLS1_CK_RSA_EXPORT1024_WITH_RC2_CBC_56_MD5
    TLS1_CK_RSA_EXPORT1024_WITH_DES_CBC_SHA
    TLS1_CK_DHE_DSS_EXPORT1024_WITH_DES_CBC_SHA
    TLS1_CK_RSA_EXPORT1024_WITH_RC4_56_SHA
    TLS1_CK_DHE_DSS_EXPORT1024_WITH_RC4_56_SHA
    TLS1_CK_DHE_DSS_WITH_RC4_128_SHA
They were defined in a long-expired IETF internet-draft:
draft-ietf-tls-56-bit-ciphersuites-01.txt
