If I started with “password”, then change it to “password2”, “password3” etc, is that easier to crack the hashes of the set of passwords than if I used only the original password?

Does having the output of hash(password1), hash(password2), etc. make it easier to crack the complete set than having only hash(password)?

  • So, this isn't about changing passwords, or cracked passwords, this is entirely about the hash? If that's what you meant originally, you could have written the question very differently (and added the hash tag)... And my answer below answers you ...

Password hashes are designed so that even small changes in text result in nearly random results. Once you add a salt, which all password hashing schemes should use, even if you used the same password, the hash would be different.
