Townsend Security Inc. is a leading data encryption and key management solutions provider. For over 20 years,
Townsend has helped companies achieve security compliance requirements with solutions including Encryption

security solutions. Towensend’s security solutions are NIST certified and meet up-to-date standards in HIPAA, PCI
andHITECHforencryptionandkeymanagementrequirements.
MicrosoftSharePoint2010supportstheuseofSQLServerEnterpriseEditionwithEncryptionKeyManagementand
Transparent Data Encryption for encrypting database content. However, many of Townsend’s clients use Remote
Blob Storage (RBS) because of its better performance and ability to overcome size limitations by not storing blobs
directly to the SQL Server. Documents stored in RBS are not encrypted by the SQL Server and RBS does not provide
any encryption and decryption functions by default. Therefore, Townsend needed a custom solution that would
provideencryptionanddecryptionfunctionswithRBSforSharePoint2010forthoseclients.
Townsend Security sought the assistance of AllianceTek, a software solutions company with experience building
customSharePointsolutionsforvariousbusinesses. AllianceTekuseditsR&DandMicrosoftCertifiedProfessionals
team for SharePoint development to create an innovative solution for Townsend. The solution includes a custom
SharePoint RBS application that incorporates Townsend’s existing encryption key retrieval library to retrieve an
encryptionkeyandencryptdocumentsstoredinRBSanddecryptretrieveddocuments.
implementation
RBS encryption was achieved by extending the RBS class to create a new custom RBS provider that encrypts and
decrypts documents. This allows Townsend’s clients to benefit from the larger size limitations of RBS while having
