Argon2CheckHash()

edit

Verifies a password against an Argon2 hash. For new code, prefer Argon2Verify() for consistent naming.

Introduced: 5.3.8.43

Requires Extension: Crypto Extension

Argon2CheckHash( input=string, hash=string );

Returns: Boolean

Argument Description
input
string, required 		edit

Input string.
hash
string, required 		edit

Argon2 hash to compare against input string

Usage Notes

edit

Originally provided by the Argon2 Extension on Lucee 5.3.8.43+ and 6.x, and now also by the Crypto Extension on Lucee 7+ (which replaces it).

For new code, prefer Argon2Verify() for consistent naming with BCryptVerify() and SCryptVerify().

Examples

edit 
    secret = createUUID();
    dump(var=secret, label="input string");
    hashed = generateArgon2Hash(secret);
    dump(var=hashed, label="generateArgon2Hash");
    decoded= argon2checkhash(secret, hashed);
    dump(var=decoded, label="argon2checkhash matches");
