WebbOne possible reason for this is SSL/TLS; versions of TLS up to v1.2 used a "signature" created from an MD5 hash concatenated with a SHA-1 hash. Such a scheme is often not compatible with the signature generation methods provided by RSA implementations, hence they rely on the RSA encryption routine to magically do the right thing. WebbSHA-1 is a mathematical algorithm to hash a certain string. It creates a one-way change from the source string to the result. It is commonly used for security and data loss, but there may be other cases. Computer programs exist to crack SHA-1 hashes by hashing random strings and storing the result. rbd ano
