I assume that the OP is refering to the Rivest, Shamir and Adleman
asymmetric encryption algorithm. Although they are commonly
used alongside each other, it is not a hashing algorithm like SHA-1.

MD5 (another hash) was invested by Rivest alone, but who the inventors
of SHA-1 where does not seem to be public knowledge, it is credited to the NSA.
(The USA's national security agency).
