Here you select the signature algorithm used by the Certificate Authority (CA) to sign the certificate. This method must be supported by the certification authority (CA) and the certificate recipient (client) as the client uses this signature to check the integrity of the certificate. Two cryptographic hash functions are relatively widespread.
- SNMP ID:
- 2.39.2.6
- Console path:
- Setup > Certificates > SCEP-CA
- Possible values:
- MD5
- Message Digest Algorithm 5: The MD5 algorithm generates a 128-bit hash value. MD5 was developed in 1991 by Ronald L. Rivest. The results reveal no conclusive information about the key. This method takes a message of any length to generate a 128-bit message digest, which is attached to the unencrypted message. The recipient compares the message digest with that determined from the information.
- SHA1
- Secure Hash Algorithm 1: The SHA1 algorithm generates a 160-bit hash value. This is used to calculate a unique checksum for any data. Generally this data makes up messages. It is practically impossible to come across two messages with exactly the same SHA value.
- SHA256
- Like SHA1 but with a 256-bit hash value.
- SHA384
- Like SHA1 but with a 384-bit hash value.
- SHA512
- Like SHA1 but with a 512-bit hash value.
- Default:
- MD5
