## Notes ## Notes
[OpenSSL 1.1.1](https://www.openssl.org/docs/man1.1.1/man1/openssl-enc.html) introduced a not backwards compatible change: the default digest to create a key from the passphrase changed from md5 to sha-256. [OpenSSL 1.1.1](https://www.openssl.org/docs/man1.1.1/man1/openssl-enc.html) introduced a not backwards compatible change: the default digest to create a key from the passphrase changed from md5 to sha-256.
Also, a new `-iter` parameter to explicitly specify a given number of iterations on the password in deriving the encryption key was added. Also, a new `-iter` parameter to explicitly specify a given number of iterations on the password in deriving the encryption key was added.
Before OpenSSL 1.1.1 this option was not available. Before OpenSSL 1.1.1 this option was not available.
Since the new parameters are more secure, `sshenc.sh` changed to adopt them, so since 2019-11-26, files encrypted with a previous version of `sshenc.sh` will not decrypt.
