Software Authentication Manager Commands on Cisco IOS XR Software

sam verify

sam verify

To use the Message Digest 5 (MD5) hash algorithm to verify the integrity of the software component on a flash memory card and ensure that it has not been tampered with during transit, use the sam verify command in EXEC mode.

sam verify {location file-system} {MD5 SHA [digest]}

Syntax Description

 

location

Name of the flash memory card slot, either disk0 or disk1.

 

 

file-system

Absolute path to the file to be verified.

 

 

 

 

 

 

MD5

Specifies a one-way hashing algorithm to generate a 128-bit hash (or message

 

 

 

digest) of the specified software component.

 

 

 

 

 

 

SHA

Specifies the Secure Hash Algorithm, a hashing algorithm that takes a message of

 

 

 

less than 264 bits in length and produces a 160-bit message digest. The large

 

 

 

message digest provides security against brute-force collision and inversion

 

 

 

attacks.

 

 

 

 

 

 

digest

(Optional) Message digest generated by the hashing algorithm, to be compared in

 

 

 

determining the integrity of the software component.

 

 

 

 

 

 

 

Defaults

 

No default behavior or values

No modification.

 

 

Release 3.2

This command was supported on the Cisco XR 12000 Series Router.

 

 

Usage Guidelines To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

Use the sam verify command to generate a message digest for a given device. The message digest is useful for determining whether software on a flash memory card has been tampered with during transit. The command generates a hash code that can be used to compare the integrity of the software between the time it was shipped and the time you received it.

For example, if you are given a flash memory card with preinstalled software and a previously generated MD5 message digest, you can verify the integrity of the software using this command:

sam verify device MD5 digest

where device is the flash device and digest is the message digest supplied by the originator of the software.
