Subject: [PATCH] fix: Changed OpenSSL check inside configure.am
|
|
|
|
In OpenSSL 1.1.0 the `EVP_MD_CTX_create()` and `EVP_MD_CTX_destroy()`
|
|
functions were renamed to `EVP_MD_CTX_new()` and `EVP_MD_CTX_free()`.
|
|
Because a check for `EVP_MD_CTX_create()` was in place inside
|
|
configure.am, building with newer OpenSSL versions could not be done.
|
|
|
|
Checking for `EVP_MD_CTX_create` function from configure.am was
|
|
replaced with a check for `CRYPTO_new_ex_data()` function.
|
|
|
|
Because a [compatibility layer][1] was introduced in OpenSSL 1.1.0,
|
|
no code changes are necessary.
|
|
|
|
Fixes: #203
