Overview
udmg-sshkey: SSH Key conversion
UDMG Server only accepts the OpenSSH format for SFTP/SSH public keys. The udmg-sshkey tool allows to convert from other format to the OpenSSH format.
The supported input formats are:
- OpenSSH authorized key line
- PEM encoded formats (PKCS8, PKCS1)
- SSH wire format (Binary ASN1 DER)
The output of the tool shows the key details and the OpenSSH format that is suitable for use during the setup of SFTP servers on UDMG:
- Key format
- Key algorithm
- Key size (only for RSA)
- SHA256 fingerprint
- MD5 fingerprint
- Conversion to authorized key line format
