WebOct 27, 2024 · Then split v into two indices: i0 = v%91, i1 = v/91. Then use a 91-element character table, and output two characters: table [i0], table [i1]. (now you can see the reason of 88: for the maximal value (8280), both i0 and i1 become 90) So this process is more complicated than base64, but more space efficient.

WebBase91, stylized as basE91, is a form of binary-to-text encoding scheme developed by Joachim Henke [1]. It divides the binary data stream into 13-bit packets which are then encoded in 2 ASCII characters [2]. Assuming eight bits per ASCII character, on average the encoded size will be ³⁄₁₆ larger than the original.
