/DigestMethod array
(Optional; PDF 1.7) An array of names indicating acceptable digest algorithms to use while signing. The value shall be one of SHA1, SHA256, SHA384, SHA512 and RIPEMD160. The default value is implementation-specific. This property is only applicable if the digital credential signing contains RSA public/private keys. If it contains DSA public/ private keys, the digest algorithm is always SHA1 and this attribute shall be ignored.
