Re: [openssl-users] enable TLS_RSA_WITH_RC4_128_MD5 in openssl 1.1.0e?

[Siyuan Xiang]

Yes, you are right. openssl binary is linking to a wrong shared library.

The code is fine, it's linking to the static library.

thanks.

Yes I am sure that it's compiled with enable-weak-ssl-ciphers

Hi Matt,

I tried the following command, it failed.  following is my command.

./config enable-weak-ssl-ciphers --prefix=/opt
make
make DESTDIR=/path/to/dir INSTALL

$ ./openssl version
OpenSSL 1.1.0e  16 Feb 2017

./openssl s_client -cipher "RC4-MD5:@SECLEVEL=0"

error setting cipher list
140369010624144:error:140E6118:SSL
routines:SSL_CIPHER_PROCESS_RULESTR:invalid command:ssl_ciph.c:1337:


./openssl ciphers "RC4-MD5:@SECLEVEL=0"

140458428679936:error:1410D0B9:SSL routines:SSL_CTX_set_cipher_list:no

However, after I change  SSL_CTX_set_XXX function orders,
TLS_RSA_WITH_RC4_128_MD5
do appear in client hello cipher list.

SSL_CTX_set_security_level(ctx, 0);
SSL_CTX_set_cipher_list(ctx, "ALL:RC4-MD5");

[openssl-users] enable TLS_RSA_WITH_RC4_128_MD5 in openssl 1.1.0e?

[Siyuan Xiang]

Hi all,

I have a legacy server only accept TLS_RSA_WITH_RC4_128_MD5 cipher.

I have a client using openssl 1.1.0e. It doesn't include
TLS_RSA_WITH_RC4_128_MD5.
I have recompiled the openssl using  enable-weak-ssl-ciphers, but it
doesn't work
but  TLS_RSA_WITH_RC4_128_SHA  is in client hello message.

It looks like all MD5 related ciphers are removed.  I tried to
use SSL_CTX_set_security_level to
set level to 0. but it doesn't work.

Do you have any idea how to enable TLS_RSA_WITH_RC4_128_MD5?

Regards,
Siyuan
