Hash Workflow

Hash Alfred Workflow to quickly hash, encode and decode strings. Selecting a result copies it to the clipboard.

Requirements

N/A

Installation

1. Download hash-workflow.alfredworkflow from the repo's releases section
2. Install in Alfred (double-click)

Setup (building the workflow manually)

1. Script Filter with keyword hash, argument optional, input as argv, script ./hash-workflow "$1". Quoting "$1" preserves the input's whitespace exactly. The "with space" option can be on or off: one leading space, the separator after the keyword, is ignored.
2. Connect it to a Copy to Clipboard output with {query}.

Usage

• hash <string> hashes and encodes the string. The default mode is encode.

• hash e <string> does the same, with encode mode stated explicitly. Use it to hash a string that itself starts with d or e , e.g. hash e d dog hashes d dog.

• hash d <string> decodes the string. Only decoders matching the input's shape are tried. Hex means an even number of 0-9a-f characters, Base64 uses its own alphabet, and URL decoding needs a %XX escape. Results are shown only if they decode to printable UTF-8.

• hash e/<algo> <string> / hash d/<algo> <string> limit the output to one algorithm or a family. : also works as the separator (e:sha256). Matching ignores case.

  • An exact name or alias picks that one algorithm; separators are optional. Examples: sha256, SHA-256, b64, base64url, url.
  • Otherwise every algorithm whose name starts with the given prefix is shown. For example, sha3 gives SHA3-256 and SHA3-512.
  • Naming a decoder skips the shape check, so hash d/b64 a000 decodes as base64 even though the input looks like hex.
  • Before typing the input, hash e/<prefix> or hash d/<prefix> lists the matching algorithms. hash e/ or hash d/ lists all of them. Pressing ↵ or ⇥ on one autocompletes it, e.g. to hash e/sha-256 .
  • hash e e/sha256 x hashes the literal string e/sha256 x.

Whitespace in the input is never trimmed. The input is hashed exactly as typed.
