A cryptographic restore process must verify file schema authenticity, validate authenticated encryption tags, and confirm that no malicious payload injection or file corruption occurred in transit. The <strong>Import Backup Tool<\/strong> restores previously exported zero-knowledge vault envelopes (Password Manager, Secure Notes, and Recovery Code Vaults) directly into your local browser storage with cryptographic verification.<\/p>\n<aside class=\"kr-world-bridge kr-world-bridge--utility\" data-kriyasya-world=\"utility\" style=\"display:block !important;width:100% !important;margin:36px 0 !important;padding:28px 32px !important;background:radial-gradient(circle at 90% 15%, rgba(14,165,233,0.12), transparent 30%), radial-gradient(circle at 10% 88%, rgba(16,185,129,0.10), transparent 30%), linear-gradient(135deg, #f0f9ff 0%, #ffffff 55%, #f0fdf4 100%) !important;border-radius:20px !important;position:relative !important;overflow:hidden !important\">\n<div style=\"display:flex;align-items:center;gap:8px;margin-bottom:12px\"><span style=\"display:inline-flex;align-items:center;padding:4px 12px;color:#0284c7;border-radius:999px;font-size:0.75rem;font-weight:700;letter-spacing:0.06em;text-transform:uppercase\">Daily Vedic &amp; Smart Utility Tool<\/span><\/div>\n<h3 style=\"margin:0 0 10px 0 !important;color:#0f172a !important;font-family:&#039;Playfair Display&#039;,Georgia,serif !important;font-size:1.6rem !important;font-weight:700 !important;line-height:1.35 !important;display:block !important\">Import Backup<\/h3>\n<p style=\"margin:0 0 20px 0 !important;color:#475569 !important;font-size:1rem !important;line-height:1.65 !important;display:block !important;max-width:720px !important\">Safely restore encrypted password vaults, secure notes, and two-factor recovery codes from zero-knowledge backup files with cryptographic integrity validation.<\/p>\n<div style=\"display:flex;align-items:center;gap:14px;flex-wrap:wrap;margin:0 !important;padding:0 !important\"><a href=\"https:\/\/kriyasya.com\/utility\/tools\/import-backup.php\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline-flex;align-items:center;gap:8px;padding:12px 28px;background:linear-gradient(135deg, #0284c7 0%, #059669 100%);color:#ffffff !important;border-radius:12px;font-weight:700;font-size:0.95rem;text-decoration:none\"><span>Restore Vault Backup \u2192<\/span><\/a><span style=\"display:inline-flex;align-items:center;gap:6px;font-size:0.82rem;font-weight:600;color:#64748b;padding:6px 12px;border-radius:8px;border:1px solid #e2e8f0\"><span style=\"display:inline-block;width:7px;height:7px;border-radius:50%;background:#10b981\"><\/span>Live Interactive Calculator \u2022 Instant &amp; Accurate<\/span><\/div>\n<\/aside>\n<h2>The Cryptographic Verification Pipeline During Restoration<\/h2>\n<p>When an encrypted JSON backup file is selected, the tool executes a four-stage client-side security pipeline:<\/p>\n<ol>\n<li><strong>Envelope Schema Validation:<\/strong> Confirms that the file matches the recognized Kriyasya vault envelope format (checking versioning, cryptographic algorithm headers, and base64 structural validity).<\/li>\n<li><strong>Cryptographic Header Extraction:<\/strong> Extracts the 16-byte PBKDF2 salt, iteration counter (600,000 rounds), and 12-byte AES-GCM Initialization Vector (IV).<\/li>\n<li><strong>Tamper Detection (GCM Authentication Tag):<\/strong> Unlike older unauthenticated modes (like AES-CBC), AES-GCM includes a 128-bit authentication tag.
