What steps will reproduce the problem?
1. Copy .gnupg/secring.gpg to sd card and import it as Secret key file.
2. Copy .gnupg/pubring.gpg to sd card and import it as Public key file.

What is the expected output? What do you see instead?
Keys are properly displayed but pass phrase to access private key is not 
accepted. Error message "Wrong pass phrase" always appear.

What version of the product are you using? On what operating system?
Version 1.0.8 on Milestone 2 (Froyo). Keys generated using gnupg 2.0.17 and 
libcrypt 1.4.6

Please provide any additional information below.
Tried with an old key DSA/ElGamal 1024/4096, an new one DSA/ElGamal 1024/4096 
and a RSA 4096. 
If I create a new one using APG menu, password is accepted to use/edit private 
key.

Actually the problem is that APG does not support other digest algorithm then 
MD5 and SHA1 to mangle passphrases (gpg --s2k-digest-algo command).
I changed password using SHA1 algo and APG was able to open the key.
So, this ticket could be change to Enhancement -> Support SHA256/384/512 as 
digest algorithm to mangle passphrases.

Regards.

I'm having this problem now. I'll have to investigate what algo was used on my 
private key. I don't know offhand.

Also --s2k-cipher-algo is not supported.
