binary

Die Argumente für diese Funktion sind fest vorgegeben. Ausser den nachfolgenden Argumenten dürfen keine weiteren verwendet werden.

Name	Typ	Required	Default Value	Beschreibung
binaryData	any	Yes		Binary data to decrypt.
key	string	Yes		Key or seed used to encrypt the string. For the CFMX_COMPAT algorithm, any combination of any number of characters; used as a seed used to generate a 32-bit encryption key. For all other algorithms, a key in the format used by the algorithm. For these algorithms, use the GenerateSecretKey function to generate the key.
algorithm	string	No	cfmx_compat	The algorithm to use to decrypt the string. Must be the same as the algorithm used to encrypt the string. CFMX_COMPAT(default): the CFML specific algorithm. This algorithm is the least secure option AES: the Advanced Encryption Standard specified by the National Institute of Standards and Technology (NIST) FIPS-197 BLOWFISH: the Blowfish algorithm defined by Bruce Schneier DES: the Data Encryption Standard algorithm defined by NIST FIPS-46-3 DESEDE: the "Triple DES" algorithm defined by NIST FIPS-46-3
IVorSalt	any	No		Initialization Vector for algorithms with Feedback Mode that is not ECB, or Salt for Password Based Encryption algorithms
iterations	number	No		number of Iterations for Password Based Encryption algorithms (ignored for all other algorithms). NIST recommends a minimum value of 1000.
precise	boolean	No	false	if set to true the input must follow the rule for that encoding a 100%, the decryptor will not try to interpret inputs that are not a 100% correct. This should be used to avoid false positives.
