Subject: Use EVP_DigestSignInit_ex and EVP_DigestVerifyInit_ex in libssl
X-Git-Tag: openssl-3.0.0-alpha1~175
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=fc69f32cd6852e60627969138be80cc665a573dd;p=oweals%2Fopenssl.git

Use EVP_DigestSignInit_ex and EVP_DigestVerifyInit_ex in libssl

We need to make sure we use the correct libctx for all operations in
libssl.
