encode Base64 string in command line








  • Encode base64 string:
    echo -n Secret | base64
    
  • Decode base64 string:
    echo -n U2VjcmV0 | base64 -D
    

Note:

When encoding, -n must be specified. otherwise, a newline character will always be appended, which will cause unexpected result.
