WebMay 7, 2024 · To address this issue, the InChIKey was introduced for Internet and database searching/indexing. It is a 27-character string derived from InChI, using a hashing algorithm. Hashing is a one-way mathematical transformation typically used to calculate a compact fixed length digital representation of a much longer string of arbitrary length. WebInChIKey is a fixed-length format directly derived from InChI. It is based on a strong hash (SHA-256 algorithm) of an InChI string. Because of the hash nature of the InChIKey, there …
