I see that the x509 command used with the –issuer_hash option returns a four byte digest value. Is there any method using OpenSSL to procure the 20-byte SHA-1 digest value of the issuer name?

use -fingerprint

(-subject_hash and -issuer_hash are used to look up CAs in a disk-based
 database, as used by the -CAdir option to various other OpenSSL commands.
 Basically, each CA is listed under its own -subject_hash, and calling
 -issuer_hash on a certificate then tells where to look for the CA
 certificate).
