HashAlgorithm

A string value that represents hash algorithms used to digest the PDF document. HashAlgorithm variables are used to configure the Digital Hashing Algorithm property in the Certify PDF operation and Sign Signature Field operation operations of the Signature service. These string values are valid:

SHA1:

The Secure Hash Algorithm that has a 160-bit hash value.

SHA256:

The Secure Hash Algorithm that has a 256-bit hash value.

SHA384:

The Secure Hash Algorithm that has a 384-bit hash value.

SHA512:

The Secure Hash Algorithm that has a 512-bit hash value.

RIPEMD160:

The RACE Integrity Primitives Evaluation Message Digest that has a 160-bit message digest algorithm and is not FIPS-compliant.
