ISO/IEC10118 (allparts) specifies hash-functions and is therefore applicable to the provision of authentication, integrity and non-repudiation services. Hash-functions map strings of bits of variable (but usually upper bounded) length to fixed-length strings of bits, using a specified algorithm. They can be used for
reducing a message to a short imprint for input to a digital signature mechanism, and
committing the user to a given string of bits without revealing this string.
NOTE The hash-functions specified in ISO/IEC10118 (allparts) do not involve the use of secret keys. However, these hash-functions may be used, in conjunction with secret keys, to build message authentication codes. Message Authentication Codes (MACs) provide data origin authentication as well as message integrity. Techniques for computing a MAC using a hash-function are specified in ISO/IEC9797‑2[1].
This document contains definitions, symbols, abbreviations and requirements that are common to all the other parts of ISO/IEC10118. The criteria used to select the algorithms specified in subsequent parts of ISO/IEC10118 are defined in Annex B of this document.
