openssl: SSL3 alert write:fatal:bad record mac by RC4-SHA

server: OPENSSL_MODULES=../providers gdb --args ./openssl s_server -tls1 -state -cert eecert.pem -key eekey.pem -cipher RC4-SHA -msg

client : OPENSSL_MODULES=../providers gdb --args ./openssl s_client -tls1 -state -cipher RC4-SHA -CAfile rootcert.pem -CAfile cacert.pem -msg

I loaded the legacy provider into the default library context as shown below legacy = OSSL_PROVIDER_load(NULL, "legacy"); if (legacy == NULL) { printf("Failed to load Legacy provider\n"); } deflt = OSSL_PROVIDER_load(NULL, "default"); if (deflt == NULL) { printf("Failed to load Default provider\n"); OSSL_PROVIDER_unload(legacy); }

And set security level 0 SSL_CTX_set_security_level(ctx, 0)

But there appeared the following error client: SSL3 alert read:fatal:bad record mac SSL_connect:error in error 0017FDF7FF7F0000:error::SSL routines::sslv3 alert bad record mac:ssl/record/rec_layer_s3.c:1615:SSL alert number 20

server: SSL3 alert write:fatal:bad record mac SSL_accept:error in error ERROR 0017FDF7FF7F0000:error::SSL routines::decryption failed or bad record mac:ssl/record/ssl3_record.c:664:

Can you give me a help,thanks!
