Subject: Continued a bit:
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=70ec39842bea8dca606bcc513f7d905dfcecacac;p=core.git
Continued a bit:
- in the wake of mcrypt being deprecated, an OpenSSL-based implementation
needs to be written. This commit marks the start for it. Please note, that
currently you don't have *ANY* encryption as the methods are unfinished
- moved DATA_PAYLOAD_SEPARATOR to EncryptableStream
- updated TODOs.txt
