Crypto backends for MIT Kerberos V5

[Arpit Srivastava]

Hi,

MIT Kerberos lists three crypto backends including OpenSSL and built-in.

1. Can somebody enumerate what are the differences between OpenSSL and
builin crypto backends ? What benefits do I have if I use OpenSSL and not
the builtin version.

2. Is builtin crypto backend completely interoperable with Windows
infrastructure (AD etc) ?

5. What version of OpenSSL is compliant with krb-1.10 onwards - because I
found some updates relates to Camellia cipher etc.

Best,
Arpit
