当我尝试执行以下 tcl 代码时,我得到了这个
执行“package require des”时找不到 package des(文件“encdec.tcl”第 1 行)
Tcl 代码
package require des
set key "12345678"; # Must be 8 bytes long
set msg "abcde"
##### ENCRYPTION
set encryptedMsg [DES::des -dir encrypt -key $key $msg]
# $encryptedMsg is a bunch of bytes; you'll want to send this around...
##### DECRYPTION
set decryptedMsg [DES::des -dir decrypt -key $key $encryptedMsg]
puts "I got '$decryptedMsg'"
如何获得该包裹?
