Skein +is a new family of cryptographic hash functions based on the +.Li Threefish +large-block cipher. +Its design combines speed, security, simplicity, and a great deal of +flexibility in a modular package that is easy to analyze. +.Li Skein +is defined for three different internal state sizes-256 bits, 512 bits, and +1024 bits-and any output size. +This allows Skein to be a drop-in replacement for the entire SHA family +of hash functions. +.Pp +The +.Fn SKEIN256_Init , +.Fn SKEIN256_Update , +and +.Fn SKEIN256_Final +functions are the core functions. +Allocate an +.Vt SKEIN256_CTX , +initialize it with +.Fn SKEIN256_Init , +run over the data with +.Fn SKEIN256_Update , +and finally extract the result using +.Fn SKEIN256_Final . +.Pp +.Fn SKEIN256_End +is a wrapper for +.Fn SKEIN256_Final +which converts the return value to a 33-character +(including the terminating '\e0') +.Tn ASCII +string which represents the 256 bits in hexadecimal. +.Pp +.Fn SKEIN256_File +calculates the digest of a file, and uses +.Fn SKEIN256_End +to return the result. +If the file cannot be opened, a null pointer is returned. +.Fn SKEIN256_FileChunk +is similar to +.Fn SKEIN256_File , +but it only calculates the digest over a byte-range of the file specified, +starting at +.Fa offset +and spanning +.Fa length +bytes. +If the +.Fa length +parameter is specified as 0, or more than the length of the remaining part +of the file, +.Fn SKEIN256_FileChunk +calculates the digest from +.Fa offset +to the end of file. +.Fn SKEIN256_Data +calculates the digest of a chunk of data in memory, and uses +.Fn SKEIN256_End +to return the result. +.Pp +When using +.Fn SKEIN256_End , +.Fn SKEIN256_File , +or +.Fn SKEIN256_Data , +the +.Fa buf +argument can be a null pointer, in which case the returned string +is allocated with +.Xr malloc 3 +and subsequently must be explicitly deallocated using +.Xr free 3 +after use. +If the +.Fa buf +argument is non-null it must point to at least 33 characters of buffer space. +.Pp +The +.Li SKEIN512_ +and +.Li SKEIN1024_ +functions are similar to the +.Li SKEIN256_ +functions except they produce a 512-bit, 65 character, +or 1024-bit, 129 character, output. +.Sh SEE ALSO +.Xr md4 3 , +.Xr md5 3 , +.Xr ripemd 3 , +.Xr sha 3 , +.Xr sha256 3 , +.Xr sha512 3 +.Sh HISTORY +These functions appeared in +.Fx 11.0 . +.Sh AUTHORS +.An -nosplit +The core hash routines were imported from version 1.3 of the optimized +Skein reference implementation written by +.An Doug Whiting +as submitted to the NSA SHA-3 contest. +The algorithms were developed by +.An Niels Ferguson , +.An Stefan Lucks , +.An Bruce Schneier , +.An Doug Whiting , +.An Mihir Bellare , +.An Tadayoshi Kohno , +.An Jon Callas, +and +.An Jesse Walker . \ No newline
