我需要構建自己的OpenSSL二進制文件,因爲隨Fedora-18提供的軟件包沒有橢圓曲線加密。我執行這些命令:構建OpenSSL時未定義的引用
./config --prefix=/home/USERNAME/bin/ssl --openssldir=/home/USERNAME/bin/ssl/openssl -fPIC zlib no-idea no-mdc2 no-rc5
make depend
make
但我有鏈接錯誤:

爲什麼要依賴?試試make並安裝。 – doptimusprime 2013-05-11 05:19:36
'。/ config'打印我需要發出'make depend' – Maxim 2013-05-11 06:04:57
你應該*不*使用'AES_encrypt'和朋友。您應該使用'EVP_ *'功能。請參閱OpenSSL wiki上的[EVP Symmetric Encryption and Decryption](https://wiki.openssl.org/index.php/EVP_Symmetric_Encryption_and_Decryption)。事實上,您應該使用經過身份驗證的加密,因爲它提供了*機密性和真實性。請參閱OpenSSL wiki上的[EVP Authenticated Encryption and Decryption](https://wiki.openssl.org/index.php/EVP_Authenticated_Encryption_and_Decryption)。 – jww 2015-05-15 20:30:34
