Generate RSA key 8192

Nov 11 '14 at 16:35

Hi, I would like to know if there is any plan to implement the key length to 8192 to be compatible with openssl



According to the ChilkatRsa documentation, the GenerateKey method accepts a range of 384 to 4096:

GenerateKey(ByVal numBits As Long) As Long Generates a new RSA public/private key pair. The number of bits can range from 384 to 4096.

However perhaps the documentation is out of date? Have you tried passing 8192 for the numBits parameter to see if it works? If not, maybe Chilkat has a comment on this issue?


Hi, I know that Chilkat do limit to 4096, my question was if there is any plan to improve that number. There are a lot of 8192 bit keys available (mostly for x509 certificate)

Also ENISA (European Union Agency for Network and Information Security) recommend for long period RSA keys (like ca certificate) the usage of keys of 15360 bits long.

So just asking if any support for longer keys is planned.


The only limitation w/ 8192 bits is in generating keys. Chilkat will see if it can support it in the next micro-version. Key lengths longer than 8192 bits will need to be researched.


Hey did you guys decided if you are going to implement the 8192 bit Key generation?

Thanks Luigi
