Question Title Signatures
Do you think that digital signature is more reliable than paper based signature?
You are required to give your opinion that whether digital signature is more reliable than paper based signature or not?
Note: Maximum 4 to 5 lines with 12 Font size in Times new Roman.
Do you think that in hash function can be decrypted and reversible?
No, they cannot be decrypted. These functions are not reversible. There is no deterministic algorithm that evaluates the original value for the specific hash.
However, if you use a cryptographically secure hash password hashing then you can may still find out what the original value was. These functions were designed to produce hash codes for big volumes of data / files. That is why they were designed to be very fast. It is relative easy to calculate MD5 and SHA1 hashes over a big number of inputs and use that to create a reverse lookup table.
Suppose you are application developer in multi-national company ABC and used hash function that converts an input values into another compressed values. Do you think that in hash function can be decrypted and reversible?
You are required to give your comments with valid reason in favor or against it.
Note: Maximum 4 to 5 lines
