Tool Introduction
TIGER encryption tool is an efficient and convenient online hash calculator, focusing on the TIGER series of hash algorithms. It supports three mainstream algorithms: TIGER-128, TIGER-160, and TIGER-192, capable of quickly converting any input data (such as plaintext, Hex, Base64, or Bytes) into a fixed-length hash value. This tool provides flexible configuration options, including custom calculation rounds, salt value addition and its position, and multiple character encoding choices, helping users generate secure and reliable data digests. Whether for data integrity verification, password storage, or other scenarios requiring hash calculation, this tool can provide powerful support.
Origin and Features of TIGER Hash Algorithm
TIGER (Tiger Hash) is a cryptographic hash function designed by Ross Anderson and Eli Biham in 1995. It was designed as an alternative to MD5 and SHA-1, aiming to provide higher security and faster computation speed, especially performing excellently on 64-bit systems. The output lengths of the TIGER series algorithms are 128 bits (16 bytes), 160 bits (20 bytes), and 192 bits (24 bytes), corresponding to the TIGER-128, TIGER-160, and TIGER-192 options in this tool. The TIGER algorithm is known for its unique structure (e.g., using 3 or 4 rounds of computation) and optimization for 64-bit processors, making it a competitive hash scheme at the time.
How to Use
- Enter the text or data you need to perform TIGER hash calculation on in the "String to be encrypted" text box.
- Select the TIGER hash algorithm you wish to use from the "Algorithm" dropdown menu, such as TIGER-128, TIGER-160, or TIGER-192.
- Based on your input data format, select the corresponding option in "Input Type", such as "Plaintext", "Hex", "Base64", or "Bytes".
- If needed, select the "Case" for the hash output result (lowercase or uppercase).
- Select the "Number of rounds", usually defaulting to 3 rounds, but 4 rounds can also be chosen.
- If you need to add a salt value, fill it in the "Salt (optional)" input box and select the "Salt Position" (prefix or suffix).
- Choose an appropriate "Character Encoding", such as UTF-8, to ensure correct parsing of the input data.
- Click the "Calculate" button (this operation is performed in the tool interface), and the tool will calculate and display the TIGER hash value according to your settings.
Input parameter format requirements:
- "String to be encrypted": Can be any text, Hex string, Base64 encoded string, or string representing a byte sequence, but must match the "Input Type".
- "Salt": Optional, can be any string.
- Other selection items should be chosen according to the dropdown menu or radio button prompts.
Output result format:
The tool will display the calculated hash values in a list, including Hex, Base64, and Bytes encoding formats.
Usage Example
Below is an example of using the TIGER encryption tool:
Operation Demonstration:
- String to be encrypted:
Hello World!
- Algorithm:
TIGER-192
- Input Type:
Plaintext
- Case:
Lowercase
- Number of rounds:
3
- Salt: Leave blank
- Character Encoding:
UTF-8
Expected Output Result:
- Hex:
075b9f7a77d7042c1613f9c31327170e53a7042e88a385f9
- Base64:
B1ufenfdBCwWE/nDETcXDlOnBOijhIX5
- Bytes: [Binary byte data, not easily displayed directly as text]
*Note: Actual output may vary slightly due to different calculation libraries. The above hash value is calculated based on the standard TIGER-192 (3 rounds) algorithm for "Hello World!" (UTF-8).
Frequently Asked Questions
- Q: What are the main functions of the TIGER encryption tool? A: This tool is mainly used to calculate TIGER-128, TIGER-160, and TIGER-192 hash values, supporting multiple input types (plaintext, Hex, Base64, Bytes), output case control, optional salt, and multiple character encodings.
- Q: What is the difference between TIGER algorithm and MD5, SHA-1? A: The TIGER algorithm was designed to provide higher security than MD5 and SHA-1, and is optimized for 64-bit processors. It provides 128-bit, 160-bit, and 192-bit outputs, while MD5 is 128-bit and SHA-1 is 160-bit. TIGER's security is relatively good, but due to its complexity, it is not as widely used as more modern algorithms like SHA-256.
- Q: How to choose the number of calculation rounds for TIGER hash? A: The TIGER algorithm usually has 3 or 4 rounds of calculation. 3 rounds is the standard configuration, and 4 rounds provide higher security but slightly higher computational overhead. In most cases, 3 rounds are sufficient. Unless there are specific security requirements, it is recommended to use the default 3 rounds.
- Q: Can I use Hex format input for TIGER encryption? A: Yes, this tool supports Hex strings as input type. Please ensure that you select "Input Type" as "Hex" and that the input string is a valid hexadecimal representation.
Notes
- Please ensure that the "Input Type" strictly matches the data format you provide in the "String to be encrypted", otherwise it may lead to calculation errors or unexpected results.
- When selecting "Plaintext" input type, be sure to confirm that the "Character Encoding" option is consistent with the actual encoding of your plaintext, as this will directly affect the final hash value.
- Salt is an effective way to improve hash security, but when using it, please ensure that the salt is properly managed and stored to avoid leakage.
- Although the TIGER algorithm is secure, for applications requiring the highest level of security, it is recommended to consider using more modern hash functions, such as SHA-256 or SHA-3.
- This tool is an online hash calculator and does not save any user input data, so please feel free to use it.
