I've enabled FIPS compliance mode in Windows 7, but now my code fails to compile with the following error:
Source file 'whatever.cs' could not be opened ('This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.')
I'm using SHA1 (hashing) and TripleDes (encryption) encryption. I also tried SHA512 and AES (256 bit key).
I can't get the project to build any more, but I need to compile it to use FIPS Compliant algorithms.

Go to Start > Control Panel > Administrative tools > Local Security Policy. The Group Policy dialog appears. Under the 'Local Policies' heading, select 'Security Options' Look for the entry, 'System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing.
In Security Settings, expand Local Policies, and then click Security Options. Under Policy in the right pane, double-click System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing, and then click Disabled.
Overview. Open up your registry editor and navigate to HKLM\System\CurrentControlSet\Control\Lsa\FIPSAlgorithmPolicy\Enabled. If the Enabled value is 0 then FIPS is not enabled. If the Enabled value is 1 then FIPS is enabled.
This has a list of FIPS compliant algorithms. A more complete list is here
FIPS compliant Algorithms:
Hash algorithms
HMACSHA1
MACTripleDES
SHA1CryptoServiceProvider
Symmetric algorithms (use the same key for encryption and decryption)
DESCryptoServiceProvider
TripleDESCryptoServiceProvider
Asymmetric algorithms (use a public key for encryption and a private key for decryption)
DSACryptoServiceProvider
RSACryptoServiceProvider
So you will need to use SHA1CryptoServiceProvider and TripleDESCryptoServiceProvider to be FIPS compliant
