Blot

Blot is a command-line interface (CLI) to compute hashes similar to tools like shasum but using a variation of Ben Laurie's objecthash combined with Multihash.

Licensed under MIT (See LICENSE).

Features

Objecthash:

• Tagged types: bool, dict, float, integer, list, null, raw, set, unicode.
• Redacted values with **REDACTED**.
• Common JSON (only when compiled with the common_json feature flag).

Multihash:

• Hashing algorithms:
  • sha1
  • sha2
  • sha3
  • blake2
    • Maximum length (blake2b-512, blake2s-256)
    • Partial length.

Custom:

• Redacted values with 0x77.
• Timestamp tagged type. Note that detection is very rough and it will not guarantee a valid time.

Usage

Compact output:

$ blot -a sha2-256 '["foo", "bar"]'

Verbose output:

$ blot -a blake2b-512 --verbose '"foo"'

Codec:  0xb240 (blake2b-512)
Length: 0x40
Digest: 0x20fb5053ecefc742b73665625613de5ea09917988fac07d2977ece1c9bebb1aa0e5dfe8e3f2ae7b30ac3b97fac511a4745d71f5d4dbb211d69d06b34fb031e60

Sequences as sets instead of lists:

blot --sequence=set -a sha3-256 '["7716209dec0a5fc4b58a6d2a89c248c8ac845fc2a42ec440ec72f5f1554d3b9507689d", "bar"]'`
