Subject: Make EVP_PKEY_[get1|set1]_tls_encodedpoint work with provided keys
X-Git-Tag: openssl-3.0.0-alpha4~175
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=6a9bd9298bd706e3a4a40ecfa1d89f65f8592c65;p=oweals%2Fopenssl.git

Make EVP_PKEY_[get1|set1]_tls_encodedpoint work with provided keys

EVP_PKEY_[get1|set1]_tls_encodedpoint() only worked if an ameth was present
which isn't the case for provided keys. Support has been added to dh,
ec and ecx keys.
