Hi! I am trying OpenSSL EVP for some AES-GCM encryption/decryption testing. Having Debian 8.4 (testing) my installed evp.h does not include the following defines I need. #define EVP_CTRL_AEAD_SET_IVLEN 0x9 #define EVP_CTRL_AEAD_GET_TAG 0x10 #define EVP_CTRL_AEAD_SET_TAG 0x11 If I set it manually it seems to work. I found it as "ctrl() values" on https://github.com/openssl/openssl/blob/master/include/openssl/evp.h. My distributions OpenSSL is 1.0.1k 8 Jan 2015. So 2 questions. - Why is it not included in my evp.h. Is it too old? - If it is too old, is it ok to define it by myself or is it a bad idea? Thanks for help! Chris
