Permissions 0644 for 'id_rsa_bblc' are too open

Question

I am running a job in jenkins. But when I create a build I get below error.

Permissions 0644 for 'id_rsa_bblc' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
bad permissions: ignore key: id_rsa_bblc
Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,password).

While googling for a solution I found that I will have to change file permission to 400 or 600. So I tried to build job again after changing permission (using both 400 and 600) but still there is no use, the error still remains.

Please help me resolve this issue.

Answer 1

You need to restrict the access rights to your rsa key

 chmod 400 ~/path-to-your-rsa-key
