Block encryption algorithms, such as AES, will produce output that is a multiple of the algorithm’s block size. For AES, the output is a multiple of 16 bytes. However, this is for the typically used cipher modes “CBC” (Cipher Block Chaining) and “ECB” (Electronic Cookbook). There are other cipher modes that turn a block algorithm into a stream cipher. See […]

This happens all the time.. Quite often, a service provider will provide instructions for HMAC generation, and will provide a hexadecimal HMAC key in the example, such as: 01A0251D601FEF3305A38B124068A001CF3F099AA187DB2886314C67CDFDEBCD This is implicitly ambiguous because there are two ways to interpret the instructions: 1) The HMAC key is composed of the ascii bytes ‘0’, ‘1’, ‘A’, ‘0’, ‘2’, ‘5’, etc. In […]
The Chilkat MailMan class can fetch emails from a POP3 server in two ways: by sequence number, or by UIDL. When an email is fetched by UIDL, or fetched in a way such that a full mapping of UIDL’s to sequence numbers was retrieved, Chilkat will add an “X-UIDL” header to the Email object that is returned. This allows for […]

This is a note for PowerBuilder programmers: Some Chilkat classes provide a SleepMs method, which is provided as a convenience. The SleepMs method puts the thread to sleep for a number of milliseconds. However, this is not the same as a PowerBuilder Yield, which “Yields control to other graphic objects, including objects that are not PowerBuilder objects. Yield checks the […]
