libcrypto from either of LibreSSL or OpenSSL. Building without libcrypto
is supported but severely restricts the available ciphers and algorithms.
- LibreSSL (https://www.libressl.org/)
- OpenSSL (https://www.openssl.org) with any of the following versions:
- 1.0.x >= 1.0.1 or 1.1.0 >= 1.1.0g or any 1.1.1
Note that due to a bug in EVP_CipherInit OpenSSL 1.1 versions prior to
1.1.0g can't be used.
- LibreSSL (https://www.libressl.org/) 3.1.0 or greater
- OpenSSL (https://www.openssl.org) 1.1.1 or greater
LibreSSL/OpenSSL should be compiled as a position-independent library
(i.e. -fPIC, eg by configuring OpenSSL as "./config [options] -fPIC"
