| 58 |
|
| 59 |
Gentoo has discontinued support for PyCrypto. We recommend that users |
| 60 |
unmerge PyCrypto: |
| 61 |
|
| 62 |
# emerge --unmerge "dev-python/pycrypto" |
| 63 |
|
| 64 |
NOTE: The Gentoo developer(s) maintaining PyCrypto have discontinued |
| 65 |
support at this time. PyCryptodome is the canonical successor to |
| 66 |
PyCrypto. |
