Goldstein Lyor reassigned SSHD-850:
-----------------------------------
Assignee: Goldstein Lyor
> Add capability to retry a failed private key decryption when client is
> decrypting private key file(s)
> -----------------------------------------------------------------------------------------------------
>
> Key: SSHD-850
> URL: https://issues.apache.org/jira/browse/SSHD-850
> Project: MINA SSHD
> Issue Type: New Feature
> Affects Versions: 2.0.0, 2.1.0
> Reporter: Thomas Wolf
> Assignee: Goldstein Lyor
> Priority: Minor
>
> In openssh, the ssh config entry NumberOfPasswordPrompts controls the number
> of times the ssh client keeps asking for a password if the one entered was
> invalid in two cases:
> # keyboard-interactive authentication, and
> # asking for passwords for encrypted private keys in identity files in
> pubkey authentication (see [openssh sources;
> sshconnect2.c|https://github.com/openssh/openssh-portable/blob/1a4a9cf/sshconnect2.c#L1380]).
> sshd-core only has support for (1) through setting the property
> {{ClientAuthenticationManager.PASSWORD_PROMPTS}} in the session's properties.
> There doesn't seem to be any support for FilePasswordProvider to make it
> respect this value.
> {{AbstractPEMResourceKeyPairParser.extractkeyPairs()}} and also
> {{BouncyCastleKeyPairResourceParser.loadKeyPair()}} call
> {{FilePasswordProvider.getPassword()}} exactly once.
> So how can I write a ssh client using sshd that asks the user
> NumberOfPasswordPrompts times? Either I'm missing something, or there is some
> support for this missing in sshd.
