step base64

Name

step base64 -- encodes and decodes using base64 representation

Usage

step base64
[-d|--decode] [-r|--raw] [-u|--url]

Description

step base64 implements base64 encoding as specified by RFC 4648.

Options

-d, --decode decode base64 input

-r, --raw use the unpadded base64 encoding

-u, --url use the encoding format typically used in URLs and file names

Examples

Encode to base64 using the standard encoding:

$ echo -n This is the string to encode | step base64
VGhpcyBpcyB0aGUgc3RyaW5nIHRvIGVuY29kZQ==
$ step base64 This is the string to encode
VGhpcyBpcyB0aGUgc3RyaW5nIHRvIGVuY29kZQ==

Decode a base64 encoded string:

$ echo VGhpcyBpcyB0aGUgc3RyaW5nIHRvIGVuY29kZQ== | step base64 -d
This is the string to encode

Encode to base64 without padding:

$ echo -n This is the string to encode | step base64 -r
VGhpcyBpcyB0aGUgc3RyaW5nIHRvIGVuY29kZQ
$ step base64 -r This is the string to encode
VGhpcyBpcyB0aGUgc3RyaW5nIHRvIGVuY29kZQ

Encode to base64 using the url encoding:

$ echo 'abc123$%^&*)_+-=~' | step base64 -u

Decode an url encoded base64 string. The encoding type can be enforced using the '-u' or '-r' flags, but it will be auto-detected if they are not passed:

$ echo YWJjMTIzJCVeJiooKV8rLT1-Cg== | step base64 -d
abc123$%^&*)_+-=~
$ echo YWJjMTIzJCVeJiooKV8rLT1-Cg== | step base64 -d -u
abc123$%^&*)_+-=~
