使用KeyczarTool創建新的密鑰集

Question

按照wiki中記錄的文檔，我試圖使用KeyczarTool來生成新的密鑰集。其他人遇到此FileNotFoundException？ KeyczarTool.jar具有rwx權限，並嘗試通過sudo運行。

從文檔

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 

輸出：

    at org.keyczar.KeyczarTool.create(KeyczarTool.java:366)

Answer 1

正如@jbtule指出你必須先創建密鑰目錄。但也包括。在斜線之前。

正確工作的命令是： $ Java的罐子KeyczarTool-0.71f-060112.jar創建--location = ./keys --purpose =隱窩-name = 「第一重點」 --asymmetric = RSA

Answer 2

與Java的當前版本keyczar需要運行之前，首先創建的目錄中的 「鑰匙」該程序。

這是一個已知問題KeyczarTool should create directories automatically。
