Which is part of openssl depends on libssl?


Asked by Clark Park on Dec 09, 2021 FAQ



libssl is the portion of OpenSSL which supports TLS ( SSL and TLS Protocols ), and depends on libcrypto . This is a C api. To use it you need to include (at least) openssl/ssl.h and to link your program with libssl library. on Debian base ( debian, ubuntu, ... ) you would need libssl-dev : apt-get install libssl-dev.
Subsequently,
This package is part of the OpenSSL project's implementation of the SSL and TLS cryptographic protocols for secure communication over the Internet. It provides the libssl and libcrypto shared libraries. Other Packages Related to libssl1.1
Indeed, OpenSSL relies on two important libraries that are part of the OpenSSL project: libssl provides the client and server-side implementations for SSLv3 and TLS. libcrypto provides general cryptographic and X.509 support needed by SSL/TLS but not logically part of it The default toolket of OpenSSL that comes with Ubuntu isn’t the latest.
Similarly,
Disadventage of installing OpenSSL develpoment libraries from source is it is not easy as installing with package manager. There are multiple steps for this. Download the OpenSSL source code from the openssl.org. You can select whatever version you want. In this example we download openssl-1.0.1.
Also Know,
TL,DR: The OpenSSL package you need in is jessie-backports. However, downgrading Debian is unsupported. The package you're trying to install depends on a package with the exact name of " libssl1.0.0 ", which is why installing libssl1.0.2 doesn't help.
