Hash

A hash function is any well-defined procedure or mathematical function that converts a large amount of data into a small datum, usually a single integer. For questions about the Twitter and Facebook # symbol, use hashtag

Pbkdf2

PBKDF2 (Password-Based Key Derivation Function 2) is a key derivation function that is part of RSA Laboratories' Public-Key Cryptography Standards (PKCS) series.

Quality | Example |
---|---|

Slower standard |
"Key derivation algorithms such as bcrypt and pbkdf2 aka rfc2898derivebytes are much slower than standard hash algorithms" from question "Rfc2898DeriveBytes vs Sha2 hash generation for passwords" |

Quicker |
"A key-stretching algorithm like pbkdf2 applies a quicker hash like sha512 thousands of times typically causing the hash generation to take 1 5 of a second or so" from question "What algorithm should I use to hash passwords into my database?" |

More |
"Pbkdf2 is more secure than a simple hash or even a salt hash" from question "TripleDES TransformFinalBlock occasionally giving 'Bad Data. ' error" |

Better plain |
"Key strengthening techniques such as bcrypt or pbkdf2 are generally considered better than plain hash since cracking them requires more resources" from question "Password Hashing" |
