3: Manage level 

plain-password: Plain text password to be encrypted. 

mode: Specifies the encryption algorithm and authentication algorithm. The two encryption algorithms 

Advanced Encryption Standard (AES), Data Encryption Standard (DES) are in descending order in 

terms of security. Higher security means more complex implementation mechanism and lower speed. 

DES is enough to meet general requirements. Message-Digest Algorithm 5 (MD5) and Secure Hash 

Algorithm (SHA-1) are the two authentication algorithms. MD5 is faster than SHA-1, while SHA-1 

provides higher security than MD5. 

z 

3desmd5: Converts a plain text encryption password to a cipher text encryption password. In this 

case, the authentication protocol must be MD5, and the encryption algorithm must be 3DES. 

z 

3dessha: Converts a plain text encryption password to a cipher text encryption password. In this 

case, the authentication protocol must be SHA-1, and the encryption algorithm must be 3DES. 

z 

md5: Converts a plain text authentication password to a cipher text authentication password. In 

this case, the authentication protocol must be MD5. Or, this algorithm can convert the plain text 

encryption password to a cipher text encryption password, In this case, the authentication protocol 

must be MD5, and the encryption algorithm can be either AES or DES (when the authentication 

protocol is specified as MD5, cipher text passwords are the same by using the encryption 

algorithms AES and DES). 

z 

sha: Converts the plain text authentication password to a cipher text authentication password. In 

this case, the authentication protocol must be SHA-1. Or, this algorithm can convert the plain text 

encryption password to a cipher text encryption password, In this case, the authentication protocol 

must be SHA-1, and the encryption algorithm can be either AES or DES (when the authentication 

protocol is specified as SHA-1, cipher text passwords are the same by using the encryption 

algorithms AES and DES). 

local-engineid: Uses local engine ID to calculate cipher text password. For engine ID-related 

configuration, refer to the snmp-agent local-engineid command. 

specified-engineid: Uses user-defined engine ID to calculate cipher text password. 

engineid: The engine ID string, an even number of hexadecimal characters, in the range 10 to 64. Its 

length must not be an odd number, and the all-zero and all-F strings are invalid.
