About Random String Generator
The random string generator creates text strings from specified character sets, useful for generating API tokens, session IDs, test data, placeholder content, or unique identifiers. Offers both standard and cryptographically secure randomness.
Customize character inclusion: uppercase letters, lowercase letters, numbers, symbols, or custom character sets. Length can range from single characters to hundreds of characters for long tokens.
All generation is client-side. Strings are created and displayed locally without transmission, critical for generating tokens, API keys, or sensitive identifiers that should remain confidential.
Frequently asked questions
Use secure mode (crypto.getRandomValues()) for tokens, API keys, session IDs, or anything security-related. Standard mode is fine for test data, mock content, or non-security applications.
Most generators let you specify exact characters to include or exclude. For example: only hexadecimal (0-9, A-F), only alphanumeric, or exclude ambiguous characters.
Longer is more secure. 32+ characters for API tokens, 16+ for session IDs. Consider that hex encoding reduces entropy per character vs full alphanumeric.
