Hi All,

For doing ntp authentication, I have used ntp-keygen command to create the
keys. But this is failing in fips enabled system with
RSA_BUILTIN_KEYGEN:bad e value error.

# ntp-keygen  -S RSA -m 2048 -p serverpassword -c RSA-SHA1 -C aes-128-cbc
Using OpenSSL version *OpenSSL 1.0.1e-fips* 11 Feb 2013
Using host cm-38 group cm-38
Generating RSA keys (2048 bits)...
RSA generate keys fails
error:04081065:rsa routines:RSA_BUILTIN_KEYGEN:bad e value
Generating host key fails

Its working fine in OpenSSL 1.0.0-fips
