### Columns
|
|
#### Algorithm
|
|
The algorithm is the hashing algorithm used to store passwords with. Default is SHA256 and is recommended.
|
|
You can change the hashing algorithm in the config.yml: under `security`, locate `passwordHash`.
|
|
|
|
#### Recommendation
|
|
The recommendation lists our usage recommendation in terms of how secure it is (not how _well_ the algorithm works!).
|
|
- Recommended: The hash algorithm appears to be cryptographically secure and is one we recommend.
|
|
- Acceptable: There are safer algorithms that can be chosen but using the algorithm is generally OK.
|
|
- Deprecated: Cannot be used anymore actively or in the near future.
|
|
- Do not use: Hash algorithm isn't sufficiently secure. Use only if required to hook into another system.
|
|
- Does not work: The algorithm does not work properly; do not use.
|
|
|
|
#### Hash Length
|
|
The length of the hashes the algorithm produces. Note that the hash length is not (primarily) indicative of
|
|
whether an algorithm is secure or not.
|
|
|
|
#### ASCII
|
|
If denoted with a **y**, means that the algorithm is restricted to ASCII characters only, i.e. it will simply ignore
|
|
"special characters" such as `ÿ` or `Â`. Note that we do not recommend the use of "special characters" in passwords.
|
|
|
|
#### Salt Columns
|
|
Before hashing, a _salt_ may be appended to the password to make the hash more secure. The following columns describe
|
|
the salt the algorithm uses.
|
|

|
|
|
|
##### Salt Type
|
|
We do not recommend the usage
|
|
of any algorithm that doesn't use a randomly generated text as salt. This "salt type" column indicates what type of
|
|
salt the algorithm uses:
|
|
- Text: randomly generated text (see also the following column, "Length")
|
|
- Username: the salt is constructed from the username (bad)
|
|
- None: the algorithm uses no salt (bad)
|
|
|
|
##### Length
|
|
If applicable (salt type is "Text"), indicates the length of the generated salt. The longer the better.
|
|
If this column is empty when the salt type is "Text", it typically means the salt length can be defined in config.yml.
|
|
|
|
##### Separate
|
|
If denoted with a **y**, it means that the salt is stored in a separate column in the database. This is neither good
|
|
or bad.
