Compatibility
|

-------------

Version 1.0.29 is compatible with 1.0pre8, 1.0 and later, but not with older

versions of tinc.
|

Version 1.0.31 is compatible with 1.0pre8, 1.0 and later, but not with older
|

versions of tinc. Note that since version 1.0.30, tinc requires all nodes in
|

the VPN to be compiled with a version of LibreSSL or OpenSSL that supports the
|

AES256 and SHA256 algorithms.
|

|
||||
|
||||
Requirements
|
||||
------------
|
||||
|
||||
Since 1.0pre3, we use OpenSSL for all cryptographic functions. So you
|
||||
need to install this library first; grab it from
|
||||
http://www.openssl.org/. You will need version 0.9.7 or later. If
|
||||
this library is not installed on you system, configure will fail. The
|
||||
manual in doc/tinc.texi contains more detailed information on how to
|
||||
install this library.
