LibreSSL是由四个部分组成：

• The  openssl(1) utility, which provides tools for managing keys,  certificates, etc.

• libcrypto: a library of cryptography fundamentals

• libssl: a TLS library, backwards-compatible with OpenSSL

• libtls: a new TLS library, designed to make it easier to write foolproof applications
