Sanitize or redact your Ruby strings!

E.g. the lorem ipsum text fully sanitized looks like this:

█████ █████ █████ ███ ████, ███████████ ███████████ ████, ███ ██ ███████ ██████ ██████████ ██ ██████ ██ ██████ █████ ██████. ██ ████ ██ █████ ██████, ████ ███████ ████████████ ███████ ███████ ████ ██ ███████ ██ ██ ███████ █████████. ████ ████ █████ █████ ██ █████████████ ██ █████████ █████ ████ ██████ ██████ ██ ██████ █████ ████████. █████████ ████ ████████ █████████ ███ ████████, ████ ██ █████ ███ ███████ ████████ ██████ ████ ██ ███ ███████.

"Deploy all ground assets to Northern Theater.".sanitize
# => ██████ ███ ██████ ███████ ██ ████████ ███████.

"Engage any combatants using IE.".redact
# => [REDACTED] [REDACTED] [REDACTED] [REDACTED] [REDACTED].

Sanitization is the process of removing sensitive information from a document or other medium, so that it may be distributed to a broader audience. When dealing with classified information, sanitization attempts to reduce the document's classification level, possibly yielding an unclassified document. Originally, the term sanitization was applied to printed documents; it has since been extended to apply to computer media and the problem of data remanence as well.

Redaction generally refers to the editing or blacking out of text in a document, or to the result of such an effort. It is intended to allow the selective disclosure of information in a document while keeping other parts of the document secret. Typically the result is a document that is suitable for publication, or for dissemination to others than the intended audience of the original document. For example, when a document is subpoenaed in a court case, information not specifically relevant to the case at hand is often redacted.
