basenc

Encode and decode with multiple base encodings.

TLDR

Encode with base64

$ basenc --base64 [file]

Encode with base32

$ basenc --base32 [file]

Decode base64

$ basenc --base64 -d [file.b64]

Use base16 (hex)

$ basenc --base16 [file]

Use base2 (binary)

$ basenc --base2 [file]

SYNOPSIS

basenc encoding [options] [file]

basenc is a unified encoding/decoding tool supporting multiple base encodings including base64, base32, base16 (hex), base2 (binary), z85, and others. It consolidates functionality previously split across multiple tools.The tool is part of GNU coreutils and provides a single interface for various encoding schemes.

PARAMETERS

--base64

Base64 encoding

--base64url

Base64 URL-safe encoding

--base32

Base32 encoding

--base32hex

Base32 with extended hex alphabet

--base58

Base58 encoding (avoids visually similar characters; useful for transcription)

--base16

Base16 (hexadecimal)

--base2lsbf

Base2 (binary) least significant bit first

--base2msbf

Base2 (binary) most significant bit first

--z85

Z85 encoding (ZeroMQ)

-d, --decode

Decode data

-w, --wrap=cols

Wrap encoded lines after cols characters (default: 76, 0 = no wrap)

-i, --ignore-garbage

Ignore non-alphabet characters

WORKFLOW

$ # Base64 encode
basenc --base64 file.bin

# Base32 decode
basenc --base32 -d file.b32

# Hexadecimal
basenc --base16 file.bin

# Binary representation
echo "A" | basenc --base2msbf
