Secure Logging Signing Algorithm

This attribute defines RSA and DSA (Digital Signature Algorithm), which have private keys for signing and a public key for verification. You can select from the following:

MD2, MD5 and RSA are one-way hashes.

For example, if you select the signing algorithm MD2 w/RSA, the secure logging feature generates a group of messages with MD2 and encrypts the value with the RSA private key. This encrypted value is the signature of the original logged records and will be appended to the last record of the most recent signature. For validation, it well decrypt the signature with the RSA public key and compare the decrypted value to the group of logged records. The secure logging feature will then will detect any modifications to any logged record.
