Description Niklas Rother 2014-03-04 10:21:47 UTC
Mono uses the exponent 17 for generated RSA keys. This is fixed in code, see https://github.com/mono/mono/blob/a31c107f59298053e4ff17fd09b2fa617b75c1ba/mcs/class/Mono.Security/Mono.Security.Cryptography/RSAManaged.cs#L96

Keys generated on .NET use the exponent 65537, this is by far the most common key.

With this constallations key exchange between mono and .NET is complicated.
