  10. Hash Algorithm should be BCrypt or SSHA256

Hash Algorithm should be BCrypt or SSHA256

Introduced in version 1.12 (12 August 2020)

A hash algorithm is used to encrypt sensitive information by converting text of the hashed string type to a hash value. Both hash algorithms BCrypt and SSHA256 are secure enough to protect passwords and alike. Mendix recommends to use BCrypt, because it is resistant to brute-force search attacks. However, due to this safeguard, the performance, whilst using BCrypt, might slow down. If you are using a high concurrency of hashing operations, you might consider switching to SSHA256.

See for more information the Mendix documentation.

Non-compliant examples:

SHA256 is not recommended to use as hash algorithm
MD5 is not recommended to use as hash algorithm

Compliant examples:

Mendix recommends to use the BCrypt hash algorithm
If you are using a high concurrency of hashing operations, you might consider using the SSHA256 hash algorithm

Configure the hash algorithm in Project Runtime Settings and select BCrypt or SSHA256.
