"Library Initialization | libcrypto Initialization" (http://wiki.openssl.org/index.php/Library_Initialization#libcrypto_Initialization) sates you can use either OpenSSL_add_all_ciphers, OPENSSL_add_all_algorithms_noconf, or you can pick what you want when initializing crypto portion of the library. For picking what you want: void MyLIB_init_crypto(void) { EVP_add_cipher(EVP_sha1()); } The earlier still holds true. Initialize and install lock on the primary thread. And take care when using static C++ objects. Jeff
