使用 base64-encode 編碼/解碼?

使用 enc -base64 選項

# send encoded contents of file.txt to stdout
openssl enc -base64 -in file.txt

# same, but write contents to file.txt.enc
openssl enc -base64 -in file.txt -out file.txt.enc
		

命令行

C:\GnuWin32\neo>openssl enc -base64 -in file.txt
SGVsbG8gV29ybGQhDQo=

C:\GnuWin32\neo>openssl enc -base64 -in file.txt -out file.txt.enc

C:\GnuWin32\neo>type file.txt.enc
SGVsbG8gV29ybGQhDQo=

C:\GnuWin32\neo>
		

通過管道操作

C:\GnuWin32\neo>echo "encode me" | openssl enc -base64
ImVuY29kZSBtZSIgDQo=

C:\GnuWin32\neo>echo -n "encode me" | openssl enc -base64
LW4gImVuY29kZSBtZSIgDQo=

C:\GnuWin32\neo>
		

使用 -d (解碼) 選項來反轉操作.

C:\GnuWin32\neo>openssl enc -base64 -d -in file.txt.enc
Hello World!

C:\GnuWin32\neo>openssl enc -base64 -d -in file.txt.enc -out file.txt
		

快速命令行

C:\GnuWin32\neo>type file.txt.enc | openssl enc -base64 -d
Hello World!

C:\GnuWin32\neo>type file.txt.enc
SGVsbG8gV29ybGQhDQo=

C:\GnuWin32\neo>echo SGVsbG8gV29ybGQhDQo= | openssl enc -base64 -d
Hello World!
