Generate SHA3-384 hashes online. SHA3-384 is the 384-bit FIPS 202 Keccak hash, offering a larger digest and a smaller sponge rate for higher security margins.
SHA3-384 produces a 384-bit (96 hex character) digest using the Keccak sponge. As the output size grows, the sponge "rate" shrinks and the "capacity" grows, which raises the security margin against generic attacks. It is a natural SHA-3 counterpart to SHA-384 for applications that want a 384-bit hash with a structurally different algorithm from the SHA-2 family.
Input:
abc
Output:
ec01498288516fc926459f58e2c6ad8df9b473cb0fc08c2596da7cf0e49be4b298d88cea927ac7f539f1edf228376d25
Why does SHA3-384 process fewer bytes per block than SHA3-256?
Larger SHA-3 outputs use a bigger capacity, which lowers the rate (block size). SHA3-384 absorbs 832 bits per permutation versus 1088 for SHA3-256.
Is SHA3-384 a replacement for SHA-384?
It can be, where you want SHA-3's independent design. Both are secure 384-bit hashes today.
How long is the output?
384 bits, written as 96 hexadecimal characters.
