Bug#848986: openssh-client: ssh-keygen fails on a four character encryption password
Package: openssh-client
Version: 1:6.7p1-5+deb8u3
Severity: minor
Dear Maintainer,
When one enters a four character passphrase to ssh-keygen it fails and says
that the passphase is too short and it needs at minimum four characters.
Contrary to the failure message, ssh-keygen accepts only passphrases with at
least five characters.
$ ssh-keygen -t rsa -b 1024 -f test1
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase): <<< entered 'test' here, 4 chars
Enter same passphrase again:
key_save_private: passphrase is too short (minimum four characters)
Saving the key failed: test1.
$ ssh-keygen -t rsa -b 1024 -f test2
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase): <<< entered 'test1' here, 5 chars
Enter same passphrase again:
Your identification has been saved in test2.
Your public key has been saved in test2.pub.
The key fingerprint is:
bd:b9:f8:87:2e:77:d8:88:50:4c:71:11:28:36:98:a6 michael@polaris
The key's randomart image is:
