Solution 1

A Web service cannot be SHA-1 encrypted, just because SHA-1 is not encryption by is a cryptographic hash function, which cannot be used for encryption and decryption in principle, period. Please see:
http://en.wikipedia.org/wiki/Cryptographic_hash_function[^],
http://en.wikipedia.org/wiki/SHA-1[^].

By the way, please read the last article: SHA-1 is considered broken and should not be used at all where security is required.

Man thank you, is not mine i never care for the security it is not our concern, but i have to connect to online service from another vendor I have good idea about f***ing these f***in encryption, but it is not the web service encrypted by itself I meant the data we be as sha1 encrypted values not plain text

thank you

That's fair. I specifically mentioned "where security is required" Hash functions can still be used when it it not required, and then SHA-1 is just fine. You see, your question about "Web site encryption" still makes me doubtful about your understanding of encryption... Do yo understand that "SHA-1 encrypted" is something which cannot be decrypted, so it cannot be used for site encryption?! You mix up something.
