# STATUS_ALIGNMENTERROR
4.0.0 4.0.0Used in the encodeData and Modules.Crypto.Cryptor methods to report an error. This means that the data you are passing is not correctly padded (specifically that the entire data length including padding is not a multiple of the block size). The most likely cause is that you are truncating your encrypted data somewhere, possibly outside of this routine.
Only reported by iOS (though the constant is still defined on Android).

# STATUS_DECODEERROR
4.0.0 4.0.0Used in the encodeData and Modules.Crypto.Cryptor methods to report an error. Input data did not decode or decrypt properly.
Only reported by iOS (though the constant is still defined on Android).
# STATUS_ERROR
4.0.0 4.0.0Used in the Modules.Crypto.Cryptor methods to report a generic error for an operation.
# STATUS_MEMORYFAILURE
4.0.0 4.0.0Used in the encodeData and Modules.Crypto.Cryptor methods to report an error with allocating memory.
Only reported by iOS (though the constant is still defined on Android).
# STATUS_PARAMERROR
4.0.0 4.0.0Used in the encodeData and Modules.Crypto.Cryptor methods to report an error with the supplied parameters or properties.
# STATUS_SUCCESS
4.0.0 4.0.0Used in the reset and release methods to report success for the operation.
# STATUS_UNIMPLEMENTED
4.0.0 4.0.0Used in the getOutputLength and various Modules.Crypto.Cryptor methods to report an error. Typically used to indicate the given algorithm/mode is not implemented in this OS version.
Android will report this status only on getOutputLength. Otherwise this status is only reported by iOS for the methods performing operations.
# TYPE_BASE64STRING
4.0.0 4.0.0Used in the encodeData and decodeData methods to specify expected string format. A Base64 encoded string.
# TYPE_BLOB
4.0.0 4.0.0Used in the encodeData method to specify expected input is a Ti.Blob instance.
# TYPE_HEXSTRING
4.0.0 4.0.0Used in the encodeData and decodeData methods to specify expected string format. A hexadecimal formatted string. Each byte is represented by 2 hexadecimal numbers.
