A federal appeals court is rejecting an appeal from a bank-fraud defendant who has been ordered to decrypt her laptop so its contents can be used in her criminal case.

Colorado federal authorities seized the encrypted Toshiba laptop from defendant Ramona Fricosu in 2010 with valid court warrants while investigating alleged mortgage fraud, and demanded she decrypt it by typing in her password. In January, U.S. District Judge Robert Blackburn ordered the woman, who faces decades in prison if convicted, to decrypt the laptop by the end of February.

Her attorney appealed, hoping to win a reprieve based on the assertion that being forced to decrypt her laptop amounts to a breach of the woman’s Fifth Amendment right against compelled self-incrimination.
