Hash Functions

This topic describes the hash functions in Graph Studio.

Typographical Conventions

This documentation uses the following conventions in function syntax:

• CAPS: Although SPARQL is case-insensitive, function names and other keywords are written in uppercase for readability.
• [ argument ]: Brackets are used to indicate optional arguments. Arguments without brackets are required.

Functions

• MD5: Returns the MD5 checksum of a string as a hexadecimal string.
• SHA1: Calculates the SHA-1 digest of a string value.
• SHA224: Calculates the SHA-224 digest of a string value.
• SHA256: Calculates the SHA-256 digest of a string value.
• SHA384: Calculates the SHA-384 digest of a string value.
• SHA512: Calculates the SHA-512 digest of a string value.
