Compatible Unicode Intrinsic Functions - IsHashEqual Method
Does the hash value match the derived value
Member of Compatible Unicode Intrinsic Functions (PRIM_LIBI.ICompatibleUnicodeIntrinsics)
Parameters
| Name | Type | Data Type | Description |
|---|---|---|---|
| Result | *Result (Optional) | Boolean | True if the values are equal |
| Hash | *Input (Optional) | Unicode String | Value to be hashed |
| Usage | *Input | Enumeration | Specifies how the Hash is used |
| Algorithm | *Input | Enumeration | Hashing algorith to be used |
Details
The IsHashEqual method tests the supplied hash value against a derived value. The Usage and Algorithmz parameters allow different hashing mechanisms to be used.
Usage Allowed Values
| Enum Value | Description |
|---|---|
| Digest | The resulting hash will be used as a message digest, generally to verify the integrity of a message and detect accidental alterations to any part of the message |
| Password | A sequence of cryptographically secure random number (salt) will be added to the input before it gets hashed to protect the hash against lookup table attacks. You would generally store the resulting password hash in your user database table so it can be verified during the login process. |
Algorithm Allowed Values
| Enum Value | Description |
|---|---|
| PBKDF2 | Password based key derivation function 2 |
| MD5 | Widely used hash function producing a 128-bit hash value |
| SCrypt | Password based key derivation function |
| SHA256 | Hash function designed by the United States National Security Agency |
