    Problem Summary
    ---------------------------------------------------------------
    While performing key operations that involve rewriting the
    keyring, the header length of any old format header packet is
    miscalculated.
    
    When importing a key which uses any algorithm that is not
    supported by EF, EF throws a NullPointerException.
    

Problem conclusion

  • EF calculates the header length of old format header packets
    as per the RFC 4880 standards.
    
    When EF encounters keys with a miscalculated header length
    while listing the keys, EF informs the user about any keys with
    a miscalculated header length.
    
    When EF encounters keys with a miscalculated header length while
    deleting any keys by keyID(-xK)/userID(-xP), EF deletes the
    specified keys as well as any keys with a miscalculated header
    length.
    
    When EF encounters a key with any algorithm that is not
    supported by EF, the following error message is displayed:
    
    Error Message: CSD0720I Unsupported asymmetric algorithm ID for
    V4 signatures: 22
    
    The following changes were made to "Using Encryption Facility
    for OpenPGP" (SA23-2230):
    
    - The following messages were added in "Chapter 5. Encryption
    Facility for OpenPGP messages":
    
        CSD0789I Key associated with the user user_id does not
        contain a valid OpenPGP certificate, delete the key and
        retry.
        Explanation: Encryption Facility encountered an invalid
        OpenPGP certificate. Data is probably corrupted.
        In the message text:
        user_id User ID
        System action: Processing continues.
        User response: Delete the invalid OpenPGP certificate.
    
        CSD0790I Key associated with the user user_id does not
        contain a valid OpenPGP certificate, deleting the key.
        Explanation: Encryption Facility encountered an invalid
        OpenPGP certificate. Data is probably corrupted.
        In the message text:
        user_id User ID
        System action: Processing continues.
        User response: None.
