Encoding details
Base64 and Base64url are encodings, not encryption. Base64url output omits padding. URL conversion uses encodeURIComponent / decodeURIComponent, so "+" remains a literal plus when decoding; it is not treated as a form-encoded space. Invalid Base64, percent sequences, and non-UTF-8 decoded bytes are rejected.
