Z85 RFC 1924 Base85 Stream Encoder Decoder

· Last updated：2026-08-05

Encode or decode bytes with ZeroMQ Z85, RFC 1924 Base85 or a validated custom alphabet in single or line-batch mode

Details

What this tool helps you do

Keeps Z85 and the RFC 1924 alphabet stream variant distinct, validates custom 85-character alphabets, supports UTF-8/hex/base64 byte views and reports partial-block padding.

Overview

Encode or decode byte data with ZeroMQ Z85, RFC 1924 Base85, or a validated custom 85-character alphabet. Enter UTF-8 text, hexadecimal, or Base64 bytes, choose the input and output views, and process one value or multiple lines.

When to use

  • Convert hexadecimal, Base64, or UTF-8 byte data into Z85 or RFC 1924 Base85 text.
  • Decode Base85 text and inspect the resulting bytes as UTF-8, hexadecimal, or Base64.
  • Process several independent values line by line or validate a custom 85-character alphabet.

How it works

  1. 1Enter the input and select Encode or Decode.
  2. 2Choose Z85, RFC 1924 Base85, or Custom alphabet, then select the input and output encodings.
  3. 3Use Single value for one item or One per line for batch conversion.
  4. 4Enable Strict Block Length to validate block sizes; the tool also reports partial-block padding when applicable.

Use cases

  • Prepare byte values for ZeroMQ systems that use the Z85 alphabet.
  • Inspect and convert RFC 1924 Base85 data during protocol or data-format debugging.
  • Apply a validated custom Base85 alphabet to line-based byte values.

Examples

1. Encode hexadecimal bytes with Z85

Developer

Background

A developer has a four-byte hexadecimal value and needs its representation in the ZeroMQ Z85 alphabet.

Problem

The hexadecimal bytes must be converted without confusing Z85 with another Base85 variant.

How to use

Enter `00010203`, choose Encode, select Z85 (ZeroMQ), set Input Encoding to Hex and Output Encoding to UTF-8, and keep Strict Block Length enabled.

Input: 00010203; Operation: Encode; Variant: Z85 (ZeroMQ); Input Encoding: Hex; Output Encoding: UTF-8; Batch Mode: Single value; Strict Block Length: enabled

Outcome

The tool returns the Z85-encoded text for the four input bytes.

2. Decode an RFC 1924 Base85 block as hexadecimal

Protocol analyst

Background

An analyst has the RFC 1924 Base85 block `009C6` and wants to inspect the decoded bytes directly.

Problem

The Base85 text needs to be decoded with the RFC 1924 alphabet and displayed as hexadecimal rather than text.

How to use

Enter `009C6`, choose Decode, select RFC 1924 Base85, set Input Encoding to UTF-8 and Output Encoding to Hex, and keep Strict Block Length enabled.

FAQ

What is the difference between Z85 and RFC 1924 Base85?

They use different Base85 alphabets. Select the variant that matches the format expected by your system.

Which input encodings are supported?

The tool accepts UTF-8 text, hexadecimal bytes, and Base64 bytes.

Which output encodings are supported?

Results can be shown as UTF-8, hexadecimal, or Base64, depending on the selected operation.

How does batch mode work?

Select One per line to encode or decode each input line independently.

What is required for a custom alphabet?

A custom alphabet must contain exactly 85 unique printable ASCII characters.
