hash - Any "out of band" hashes in MD* or SHA-*? -

do of mutual hash algorithms define "out of band" hash code, i.e. 1 guaranteed never result of algorithm?

neither md* or sha-* family of algorithms has out of band hash value.

if wish implement yourself, can utilize next logic:

select random hash value out of band value. compute hash. if hash value (improbably) turns out out of band hash value, assign hash value.

in pseudocode:

outofbandhash = 0xdeadbeefdeadbeefdeadbeefdeadbeef h = hash(stuff) if h = outofbandhash h = outofbandhash + 1
