Cryptographic Hashing

Meaning

Cryptographic hashing is a data security process that transforms an input of any size, such as sensitive patient health data or a clinical report, into a fixed-size string of characters called a hash value or digest. This transformation is one-way, meaning the original data cannot be reconstructed from the hash, making it an essential tool for ensuring data integrity and privacy. In the context of hormonal health data management, it allows for the verification of data authenticity and the secure pseudonymization of personal identifiers. The resulting hash serves as a unique, non-reversible fingerprint for the data.
