我想使用 openssl 加密文件。我可以通过使用
openssl des3 -salt -in /pritom/uaeyha_com.sql -out /pritom/a.ss
当我运行这个命令时,它从我这里得到了两次密码。我想用脚本设置密码,我用过
openssl des3 -salt -in /pritom/uaeyha_com.sql -out /pritom/a.ss -pass pritom
但它给了我以下错误:
Invalid password argument "pritom"
Error getting password
我现在可以做什么?
最佳答案
尝试这样的事情 -
openssl des3 -salt -in /pritom/uaeyha_com.sql -out /pritom/a.ss -pass pass:pritom

PASS PHRASE ARGUMENTS<br/> Several commands accept password arguments, typically using -passin and -passout for input and output passwords respectively. These allow the password to be obtained from a variety of sources. Both of these options take a single argument whose format is described below. If no password argument is given and a password is required then the user is prompted to enter one: this will typically be read from the current terminal with echoing turned off.
pass:password
the actual password is password. Since the password is visible to utilities (like 'ps' under Unix)
this form should only be used where security is not important.
env:var obtain the password from the environment variable var. Since the environment of other processes is
visible on certain platforms (e.g. ps under certain Unix OSes) this option should be used with
caution.
file:pathname
the first line of pathname is the password. If the same pathname argument is supplied to -passin and
-passout arguments then the first line will be used for the input password and the next line for the
output password. pathname need not refer to a regular file: it could for example refer to a device
or named pipe.
fd:number read the password from the file descriptor number. This can be used to send the data via a pipe for
example.
stdin read the password from standard input.
