Falha ao carregar o “Intel Accelerator OpenSSL Engine”

Question

Queremos testar o desempenho desse mecanismo Intel para ver o quanto ele pode melhorar o desempenho do openssl.

Nós compilamos o openssl 1.0.0 por etapas padrão:

$. / config; faço ; make install

e compile o Intel Engine:

$ make

Seguindo as instruções no arquivo README,

env OPENSSL_ENGINES='pwd' openssl speed -engine intel-accel -evp rc4

Temos erros:

# env OPENSSL_ENGINES='pwd' openssl speed -engine intel-accel -evp rc4
invalid engine "intel-accel"
