It should be: const EVP_CIPHER *evp_gcm = EVP_aes_128_gcm(); Although, that really shouldn't be necessary and your original version looks ok. What doesn't look quite right is the "&_ctx" bit. In 1.1.0 an EVP_CIPHER_CTX is an opaque type. You cannot allocate concrete instances of it directly. Where previously you might have had: EVP_CIPHER_CTX _ctx; EVP_CIPHER_CTX_init(&_ctx); EVP_EncryptInit_ex(&_ctx, EVP_aes_128_gcm(), NULL, NULL, NULL); You now need to do: EVP_CIPHER_CTX *_ctx; _ctx = EVP_CIPHER_CTX_new(); EVP_EncryptInit_ex(_ctx, EVP_aes_128_gcm(), NULL, NULL, NULL); ... EVP_CIPHER_CTX_free(_ctx); I have omitted error checking code for brevity.
