Limitations and common mistakes

Base58 is an encoding, not encryption. Decoding requires valid UTF-8; arbitrary binary payloads may be rejected.
Combined input is bounded to 150,000 characters; output text is bounded to 1.2 million characters. Some algorithms impose smaller limits, stated in their error messages.
