My understanding is that 3DES is best used for bulk data encryption applications such as those listed below when confidentiality is required, while SHA-1 is a hashing algoritm best employed when applications require data integrity assurance and data origin authentication. SHA-1 produces a 160-bit output called a message digest which is then input into Digetal Signature Algoritm (DSA) which generates or verifies the signature of the message. The same hash algorithm must be used by the verifier of a digital signature as was used by the creator of the digital signature.
