Hexadecimal Token

technology.cryptographic.token_hex

Random token as hex string (e.g., secure session tokens). Distinguished from cryptographic hashes by variable length that does NOT match standard hash lengths (32=MD5, 40=SHA1, 64=SHA256, 128=SHA512). Tokens are typically 16-48 hex chars at non-standard lengths.
