ra_key leaked

[jmp0x7c00]

ra_key is security-critical and it is declared here:

sgx_wechat_app/Server/Enclave/Enclave.cpp

Line 121 in 56a8d55

sgx_ra_key_128_t ra_key;

but it is leaked here by console printing and privileged attackers can get it without effort:

sgx_wechat_app/Server/Enclave/Enclave.cpp

Line 130 in 56a8d55

feprintf("ra key:%s\n", hexstring(&ra_key, sizeof(ra_key)));
