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"
Error in cipher list
140458428679936:error:1410D0B9:SSL routines:SSL_CTX_set_cipher_list:no
cipher match:ssl/ssl_lib.c:2018:
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");
Regards,
Siyuan
