Dispnet Hash

Dispnet Hash produces a self descripting hash for easy backwards compatibility. The hash format follows the TLV (type-length-value) pattern.

• First 2 characters are the hash type as integer with a leading 0 (Default is 01 which is Blake3 hash).
• Then come 4 characters as integer with leading 0 which is the length of the bytes from the digest.
• Digest value as hex.

Supported hash algorithm

• Blake3
• CRC32
• Argon2

Usage

Create a hash

rust let dispnet_hash = DispnetHash::new("test".as_bytes()); let display_hash = format!("{}", dispnet_hash); assert_eq!(display_hash, "0100324878ca0425c739fa427f7eda20fe845f6b2e46ba5fe2a14df5b1e32f50603215");

Create a hash with hash type

rust let dispnet_hash = DispnetHash::create(HashType::CRC, "test".as_bytes(), None); let display_hash = format!("{}", dispnet_hash); assert_eq!(display_hash, "02001032323538363632303830");

Get hash parts

rust let dispnet_hash = "0100324878ca0425c739fa427f7eda20fe845f6b2e46ba5fe2a14df5b1e32f50603215".parse::<DispnetHash>().unwrap(); assert_eq!(dispnet_hash.hash_type, HashType::Blake3); assert_eq!(dispnet_hash.digest_length, 32); assert_eq!(dispnet_hash.digest_value.len(), 32);

Verify Argon2 hash with value

rust assert!(DispnetHash::verify("030084246172676f6e326924763d3139246d3d343039362c743d332c703d31244d54497a4e4455324e7a6724686f56354d494638596a39746b39356c467365546279554a6e393336484944586754685533637065643151", "test".as_bytes()));
