Read/write encrypted ASN.1 PEM files

_Convert::PEM_ reads and writes PEM files containing ASN.1-encoded objects. The files can optionally be encrypted using a symmetric cipher algorithm, such as 3DES. An unencrypted PEM file might look something like this: -----BEGIN DH PARAMETERS----- MB4CGQDUoLoCULb9LsYm5+/WN992xxbiLQlEuIsCAQM= -----END DH PARAMETERS----- The string beginning 'MB4C...' is the Base64-encoded, ASN.1-encoded "object." An encrypted file would have headers describing the type of encryption used, and the initialization vector: -----BEGIN DH PARAMETERS----- Proc-Type: 4,ENCRYPTED DEK-Info: DES-EDE3-CBC,C814158661DC1449 AFAZFbnQNrGjZJ/ZemdVSoZa3HWujxZuvBHzHNoesxeyqqidFvnydA== -----END DH PARAMETERS----- The two headers ('Proc-Type' and 'DEK-Info') indicate information about the type of encryption used, and the string starting with 'AFAZ...' is the Base64-encoded, encrypted, ASN.1-encoded contents of this "object." The initialization vector ('C814158661DC1449') is chosen randomly.
