Secondary information and sharing actions for this public tool.
Generate a SHAKE digest for each text value or uploaded file. Choose SHAKE128 or SHAKE256 and an output length from 1 through 1,048,576 bytes; the default is 32 bytes. Results include raw digest bytes and lowercase hexadecimal text.
SHAKE is the extendable-output function from NIST FIPS 202. Unlike fixed-length SHA3-256 or SHA3-512, SHAKE can produce as many output bytes as the caller requests. The 128 and 256 names identify the security-strength variant, not a fixed digest length.
SHAKE is a one-way cryptographic function, not encryption, and plain SHAKE is not designed for password storage. Use SHA3 when a fixed-length SHA-3 digest is required.
