I am trying to encryption a string using SHA1 encryption. For encryption, we use a combination of AES-256 encryption and RSA encryption. RSA up to 4096-bit and DSA SHA1 up. - don't forget that different hash algorithms can be used depending on your database version. The basic difference between hashing and encryption is that hashing converts the data to message digest or hash, which is a number generated from a string of text while encryption uses encryption algorithms and a key to convert the message to transmit into an unrecognizable format. The input string encoding is expected to be in UTF-8. Some consider SHA1 (11g) to be "no longer secure enough" - but this will ultimately depend on your business requirement. Applied to SHA-1, this means the strength of SHA-1 is more equated to a string that is 280, which means only about half of the effort is required to find a collision. The problem with this is that strings encrypted with phpseclib won't be able to be decrypted by OpenSSL. This means that given a hash H(X), an attacker can find the value of H(pad(X) + Y), for any other string Y, without knowing X.
