使用KeyczarTool创建新的密钥集

Question

按照wiki中指出的文档，我试图使用KeyczarTool来生成新的密钥集。还有人遇到过FileNotFoundException吗?KeyczarTool.jar具有rwx权限，并尝试通过sudo运行。

从文档

Command Usage:
create --location=/path/to/keys --purpose=(crypt|sign) [--name="A name"] [--asymmetric=(dsa|rsa|ec)]
    Creates a new, empty key set in the given location.
    This key set must have a purpose of either "crypt" or "sign"
    and may optionally be given a name. The optional version 
    flag will generate a public key set of the given algorithm.
    The "dsa" and "ec" asymmetric values are valid only for sets
    with "sign" purpose.

Cmd:

$ java -jar KeyczarTool-0.71f-060112.jar create --location=/keys  --purpose=crypt -name="first key" --asymmetric=rsa   

输出:

org.keyczar.exceptions.KeyczarException: Unable to write to: /keys/meta

Answer 1

对于当前版本的java keyczar，需要在运行程序之前先创建目录"keys"。

这是一个已知问题KeyczarTool应该自动创建目录。

Answer 2

正如@jbtule好心指出的，您必须首先创建键dir。但也包括。斜杠之前。

正确的工作命令是:$ java -jar KeyczarTool-0.71f-060112.jar创建——location=。/keys——purpose=crypt -name="first key"——asymmetric=rsa
