I added a reference for this, but the OpenSSL fact should still be sourced and cleaned up. As of now it's still contradictory, but at least there's a reference that it expired. Thanks. 71.142.208.226 (talk) 09:19, 31 January 2008 (UTC)[reply]

Strings zero-terminated?[edit]

Are the strings in the example zero-terminated? 71.142.208.226 (talk) 08:36, 31 January 2008 (UTC)[reply]

In a sense they are: All strings are padded with zeros until they reach a multiple of the blocksize (8 bytes). As none of them already are a multiple of the blocksize, at least one zero is added. 93.159.251.115 (talk) 14:46, 28 November 2018 (UTC)[reply]
