Hi all, I was wondering if is at all possible to discover a password one char at a time.
That's not possible for hashed passwords. The hash functions are built in a way that similar strings are transformed to entirely different hashes. i.e. MD5: t: b7269fa2508548e4032c455818f1e321 te: 08ee1f3976fd6ce68c21f3500400f8eb tes: 064ef34b174ff14b43acc2e7dce0c9e7 test: d8e8fca2dc0f896fd7cb4cb0031ba249 All practically used hash functions share this important property and practically all passwords are stored in a hashed form. Such a decryption scheme would only work for character-wise encryption like a Caesar or Vigenere cryptosystem and not on a hash. Greetings, Martin Krämer
