SHA-224 (Secure Hash Algorithm 224-bit) is a cryptographic hash function that produces a 224-bit (28-byte) hash value. This hash is typically rendered as a 56-digit hexadecimal number.
Key characteristics of SHA-224:
- Always produces a fixed-size output (224 bits)
- Same input always yields the same hash
- Small changes in input result in vastly different hashes
- One-way function (cannot derive original input from hash)
- High collision resistance
Security Note: SHA-224 is technically a truncated version of SHA-256, designed to provide a security level of 112 bits against collision attacks, making it suitable for applications that require security but with a smaller output size.
- Digital Certificates: Used in certificates where the larger SHA-256 isn't necessary but stronger security than SHA-1 is needed
- Digital Signatures: In systems requiring a balance between security and output size
- TLS/SSL: As a more secure alternative to older hashing algorithms
- Data Integrity: Verifying the integrity of data where a shorter hash is preferred
Example SHA-224 hash:
Text: Hello World!

Position of SHA-224 among hash functions:
SHA-224 is part of the SHA-2 family designed by the NSA. It's essentially SHA-256 truncated to 224 bits, offering a security level of 112 bits against collision attacks. SHA-224 was designed to match the security strength of 3DES encryption, providing an alternative where a smaller output size than SHA-256 is desired. It offers a good balance between security and output length, making it suitable for applications where space efficiency matters but strong security is still needed.
