Can a digital signature change for the same input data PKCS7 / SHA256

Viewed 38

Conceptually, can a digital signature vary if it is generated multiple times for the same input data with SHA256 hashing and PKCS7 formatting.

Thank you for any help.

If data is same, SHA256 hash would be same and PKCS7 signature, using same private/public key pair, may be same unless it contains time stamping.
