rewrapping

Rewrapping refers to the process of removing an existing outer layer of protection, packaging, or encryption around an object or data and applying a new wrapper. The term is used in multiple fields and implies replacing the current wrap without altering the underlying item or content.

In packaging and logistics, rewrapping involves removing damaged or outdated packaging and applying new wrap, such as shrink film or protective coverings. It is used to secure items for retail, maintain tamper evidence, or standardize branding. Rewrapping can be performed manually or by automated equipment. Key considerations include material compatibility, barrier properties, labeling accuracy, and compliance with safety or handling regulations.

In information security, rewrapping means reencrypting a previously wrapped (encrypted) key under a different key, typically during key rotation or rekeying of a data encryption key. The wrapped data remains inaccessible without the new key, and the operation is managed by key management systems or hardware security modules. Rewrapping is a standard technique for maintaining data protection while updating cryptographic material.

In computing and publishing, rewrapping may also describe reformatting text that is wrapped to a certain line width to suit a different display or format constraint. This usage is common in preparing content for various devices, data formats, or editorial standards.
