+Enable legacy support even when the libgcrypt library is in FIPS 140-2
+mode. The legacy mode of libgcrypt allows the use of all ciphers,
+including non-approved ciphers. This mode is needed when for legacy
+reasons a message must be encrypted or decrypted. Legacy reasons for
+decryptions include the decryption of old messages created with a
+public key that use cipher settings which do not meet FIPS 140-2
+requirements. Legacy reasons for encryption include the encryption
+of messages with a recipients public key where the recipient is not
+bound to FIPS 140-2 regulation and therefore provided a key using
+non-approved ciphers. Although the legacy mode is a violation of strict
+FIPS 140-2 rule interpretations, it is wise to use this mode or
+either not being able to access old messages or not being able
+to create encrypted messages to a recipient that is not adhering
+to FIPS 140-2 rules.
