How to authorize to CRaSH using ssh and key

Question

There is a library called CRaSH, that was integrated in spring boot. The docs says, that in order to connect with ssh using key, you must add 2 lines of code in config (link) and write path to a pem key

So, I added those lines, like:

shell.auth=key
shell.auth.key.path=/home/user/.ssh/id_rsa

When I try to connect, it says permission denied (public key) When I change id_rsa to id_rsa.pub it crashes on startup with exception. Maybe because it's not pem key So, I tried to convert it

openssl req -x509 -key id_rsa -nodes -days 365 -newkey rsa:2048 -out id_rsa.pem

it results to: Key type org.bouncycastle.cert.X509CertificateHolder not supported On windows with keys generated by puttygen the picture is almost the same What I'm doing wrong?

This might be quite late, but this setup helps me to connect with ssh and key to a crash shell (version 1.3.1):

• I convert my openssh/putty key to pem

  openssl rsa -in authorized.rsa -outform pem -pubout > authorized.pem

• Then I configured crash via spring:

  <bean class="org.crsh.spring.SpringWebBootstrap">
  <property name="config">
      <props>
          <prop key="crash.auth">key</prop>
          <prop key="crash.auth.key.path">WEB-INF/sshd/authorized.pem</prop>
          <!-- ... -->
      </props>
  </property>
  

After starting my server it is possible to connect with putty:

plink -i authorized.ppk -P 12345 -ssh admin@localhost
