The SecExMail keys are stored in conventional text files ending in "#.pubrsa" and "#.privrsa" for public keys and private keys respectively. Files are divided into an administrative segment and a data segment. The administrative segment contains information required by SecExMail for key management. Administrative Segment
The data section is comprised of a single RSA key in base 64 encoded format. New lines in the data section are denoted by a single linefeed ( ASCII character 10 ). Private RSA keys are stored in 3DES encoded, chained block cipher format and protected with a passphrase.  |
