💡Tips & Knowledge
- •Base64 encodes binary/image data as text, commonly used in email attachments and data URIs
- •URL encoding converts Japanese and special characters to percent-encoding (%E3%81%82, etc.)
- •Hashes (MD5, SHA-256, etc.) are one-way conversions used for tamper detection and password storage
