SHA-384 is a type of cryptographic hash function that churns out a 384-bit hash value. It’s a member of the SHA-2 family, crafted by the NSA to offer better security than its forerunners.
SHA-384 takes any input and transforms it into a 384-bit hash, which appears as a string of 96 hexadecimal digits. It processes data in 1024-bit blocks, using a mix of bitwise operations to do so.
SHA-384 employs a combination of operations like bitwise logical functions, modular additions, and compression functions to transform a message into a secure hash.
Yes, SHA-384 is considered secure against common cryptographic attacks, such as collision and pre-image attacks, making it a reliable choice for modern security needs.
SHA-384 is preferred when you need stronger security than what SHA-256 offers, but don’t require the full output size of SHA-512. It strikes a nice balance between security and performance.
Alternatives include other cryptographic hash functions like SHA-256, SHA-512, and the SHA-3 variants, depending on your specific security needs and constraints.
The encryption time for SHA-384 can vary depending on the size of the input and the computing power available. However, it’s designed to be quick and efficient for today’s computing standards.
No, SHA-384 is a hash function, not an encryption algorithm. It’s a one-way process, meaning once data is hashed, it cannot be reversed or decrypted back to its original form.
Both are part of the SHA-2 family, but SHA-512 produces a longer, 512-bit hash, which could be seen as more secure than the 384-bit hash from SHA-384.
SHA-384 is widely used in various security applications and protocols, such as SSL certificates, cryptographic signatures, and software distribution controls, where strong integrity is crucial.
