ECIES encrypt use interactive prompt:

$ sghcrypto e hello
✔ ecies
✔ Public Key(64 bytes): ********************************************************************************************************************************
ecies encrypt hello ===> 0x04f30a03ae0ac8fcc6c8bba087ec27c42acef5d3ed870586a4a681e53fd5084a0a465c6557691acc3f732e144c858321ddee9e7e4c6c1312e1c0cd348611bf7925c80ef4dacf2ec2e166e5701fee77c4814287bd9a251895a252671fee8f8165ec54350f6bf1f00af34b70262a98c17ce3d1f9a428e9

ECIES decrypt use interactive prompt:

$ sghcrypto d 0x04f30a03ae0ac8fcc6c8bba087ec27c42acef5d3ed870586a4a681e53fd5084a0a465c6557691acc3f732e144c858321ddee9e7e4c6c1312e1c0cd348611bf7925c80ef4dacf2ec2e166e5701fee77c4814287bd9a251895a252671fee8f8165ec54350f6bf1f00af34b70262a98c17ce3d1f9a428e9

AES encrypt use interactive prompt:

$ sghcrypto e hello
✔ aes
✔ AES Key(16 bytes): ****************
aes encrypt hello ===> AMCHTDF-q0jKdiXuNvoKcXYWvrx9HnDDLRriC6QVuFk

AES decrypt use interactive prompt:

$ sghcrypto d WGM7Dteil6I1WDByRV3a2-yeXvD01YmXgIQUHYmOIhc
✔ aes
✔ AES Key(16 bytes): ****************
aes decrypt WGM7Dteil6I1WDByRV3a2-yeXvD01YmXgIQUHYmOIhc ===> hello

AES encrypt use aeskey and alg flag:

$ sghcrypto e hello -aeskey 1234567890123456 --alg aes
aes encrypt hello ===> u1S3RUI5MTi2Yz_HBgkCIXhE25jAFUON1TeJuHAmUWc

AES decrypt use key flag:

$ sghcrypto d u1S3RUI5MTi2Yz_HBgkCIXhE25jAFUON1TeJuHAmUWc -aeskey 1234567890123456 --alg aes
aes decrypt u1S3RUI5MTi2Yz_HBgkCIXhE25jAFUON1TeJuHAmUWc ===> hello

Use CRYPTO_ALG,AES_KEY,PRIVATE_KEY,PUBLIC_KEY env also support:

Windows

$ set CRYPTO_ALG=aes
$ set AES_KEY=1234567890123456
$ sghcrypto e hello
aes encrypt hello ===> Rs_jvGfUZFefVFiiUhkMCnkRLQuYuRkcDVYPtL9RZAI
