It can retrieve the hidden file using the same private seed, verify seal integrity, or generate a clean cover with the hidden payload removed. It supports PNG, PDF, DOCX, and XLSX files up to 6 MB each and 10 MB combined when sealing. Selected files are sent to PureCipher's hosted OmniSeal service for processing. OmniSeal does not summarize content, recover passwords, or provide general-purpose encryption.",
