    2727== Use in VISTA outside of the VA ==
    2828The FOIA process removes sensitive security related algorithms from VISTA. As a result, those using VISTA outside of the Veteran's Administration have had to supplement this. I have surveyed all the external VISTAs and here is what I found on how they were replaced:
    29 ||Item||WorldVistA||OpenVista||vxVista||
    30 ||Access/Verify Hash||Reversible Hash||None||MD5 Hash
     29||Item||WorldVistA||!OpenVista||vxVista||
     30||!Access/Verify Hash||Reversible Hash||None||MD5 Hash
    3131||Electronic Signature Hash||None||Restore VA Routine||MD5 Hash
    32 ||Encryption/Decryption||None||Restore VA Routine||Blowfish symmetric block cipher
    33 
    34 As you can see from this table, both OpenVista and WorldVistA have done badly (it's not known whether the OpenVista version is even legal) while vxVista has done the best.
     32||!Encryption/Decryption||None||Restore VA Routine||Blowfish symmetric block cipher
     33
     34As you can see from this table, both !OpenVista and WorldVistA have done badly (it's not known whether the !OpenVista version is even legal) while vxVista has done the best.
