About Base58 Encoding

Design Principles

  • Alphabet: 58 characters (1-9, A-Z, a-z minus 0, O, I, l)
  • No Ambiguity: Excludes visually similar characters
  • Case Sensitive: Uses both uppercase and lowercase
  • No Padding: Unlike Base64, no padding characters needed

Excluded Characters

0
Zero
O
O
I
I
l
l

These characters are excluded to prevent transcription errors

Common Applications

  • • Bitcoin: Wallet addresses and private keys
  • • IPFS: Content-addressed file system hashes
  • • Flickr: Short URL generation
  • • MongoDB: ObjectId string representation

Advantages vs Base64

  • • More human-friendly (no confusing characters)
  • • Better for manual transcription
  • • Shorter than hex for the same data
  • • No special URL encoding needed
