Introduction
Hashing is a common way to generate a fixed length representation of data. A hash function takes input data and produces a value known as a hash, digest, or checksum.
FlagsDev Text Hash Generator allows you to generate hashes from text directly in your browser. You can enter or paste text and generate hashes using multiple commonly used hashing algorithms.
This guide explains how text hashing works, which algorithms are supported, and how to understand and use the generated hash values.
What is hashing?
Hashing is the process of passing data through a hash function to produce a deterministic value called a hash. The same input produces the same hash when the same algorithm and encoding are used.
A small change in the input can produce a substantially different hash value. This property makes hashes useful for comparing data, checking integrity, identifying changes, and other technical workflows.
Hashing should not be confused with encryption. Encryption is designed to allow authorized parties to recover the original data, while cryptographic hash functions are generally designed as one way functions.

Supported hash algorithms
Text Hash Generator supports six hashing algorithms. Each algorithm produces a hash with different characteristics and output length.
MD5
MD5 produces a 128-bit hash, commonly represented as a 32-character hexadecimal value. MD5 is considered cryptographically broken and should not be used for modern security-sensitive applications.
SHA-1
SHA-1 produces a 160-bit hash, commonly represented as a 40-character hexadecimal value. SHA-1 has known practical collision weaknesses and is not recommended for new security-sensitive applications.
SHA-256
SHA-256 produces a 256-bit hash, commonly represented as a 64-character hexadecimal value. It is widely used for modern integrity and cryptographic applications.
SHA-384
SHA-384 produces a 384-bit hash, commonly represented as a 96-character hexadecimal value. It belongs to the SHA-2 family.
SHA-512
SHA-512 produces a 512-bit hash, commonly represented as a 128-character hexadecimal value. It is part of the SHA-2 family and is commonly used where a larger digest is required.
SHA-3
SHA-3 is a member of the SHA-3 family standardized by NIST. FlagsDev generates a SHA-3 digest for the supplied text.
MD5 and SHA-1 are not recommended for security
How to hash text
Follow these steps to generate hashes from text using the FlagsDev Text Hash Generator.
Open the Text Hash Generator
Open the Text Hash Generator.
The tool provides a text input field and displays the generated hash values for the supported algorithms.
Enter your text
Type or paste the text you want to hash into the input field.
The input can contain ordinary text, numbers, symbols, or other Unicode characters.
Generate the hashes
Start the hashing operation after entering your text.
The tool generates hash values using the supported algorithms and displays the results separately.
Review the output
Review the generated values and select the algorithm that matches your intended use case.
Hash outputs are deterministic, so the same input should produce the same result when processed using the same algorithm.
Copy a hash value
Copy the required hash value when you need to compare it, store it, or use it in another application.
Make sure you copy the complete hash without accidentally adding spaces or changing any characters.
Understanding hash output
Hash values are commonly displayed as hexadecimal strings. The length of the output depends on the selected hashing algorithm.
Algorithm
MD5: 128 bits
SHA-1: 160 bits
SHA-256: 256 bits
SHA-384: 384 bits
SHA-512: 512 bits
SHA-3: 256-bit digest
Common hexadecimal length
MD5: 32 characters
SHA-1: 40 characters
SHA-256: 64 characters
SHA-384: 96 characters
SHA-512: 128 characters
SHA-3: 64 characters
The hash value is determined by the exact input. Even a small difference in the input, such as an additional space, different capitalization, or a changed character, can result in a completely different hash.
Tips for text hashing
- Use the same hashing algorithm when comparing two hash values.
- Make sure the input text is exactly the same when verifying a hash.
- Watch for leading spaces, trailing spaces, line breaks, and capitalization because they can change the resulting hash.
- Use SHA-256, SHA-384, SHA-512, or SHA-3 for modern cryptographic use cases where an appropriate cryptographic hash is required.
- Do not treat a hash as encryption. A normal hash function is not intended to be decrypted back into the original text.
- Do not use general-purpose hash functions such as MD5 or SHA-1 for password storage. Passwords require dedicated password hashing algorithms designed for that purpose.

Browser based processing
This can be useful when working with text that you prefer to keep on your device. However, always verify the specific workflow and avoid sharing sensitive information unnecessarily.
